Mothers hailing from different cultures on every continent have been “wearing” babies upon their own bodies for centuries. Traditionally, baby-wearing is a convenient and pragmatic method to keep track of little ones, while continuing activities of daily life and maintaining the intimacy of mother and child.
Nowadays in North America, baby-carrying cloths are trendy accessories that are marketed under brands like Moby Wrap, Boba Wrap, and Baby K’Tan. But why limit baby-wearing slings, wraps, and carriers to human babies? We decided to make our own wrap… for our pup Mimi!
The idea actually began during our hikes. Mimi is thrilled to scramble up rocks and down paths but, as every one of our human strides is ten of her Maltese steps (times four paws), she tuckers out! We made our own wrap, so that we can carry Mimi during strenuous portions of the trek. The wrap started out as a silly but actually has turned into a very pragmatic piece of equipment! Here is our incredibly simple and quick project – you can make one too!
1. Select 2.5y (90”) of cloth. Our choice was a whimsical folk pattern of quirky birds and playful flowers. This is a 100% cotton fabric that is strong enough to support Mimi’s weight. Ffun fact: Her weight is less than that of most newborns! This fabric also has just a little bit of elasticity for our comfort and for hers. Finally, it is conveniently machine-washable.
2. Cut the cloth length-wise. Most bolts of fabric are either 45” or 60”. If your original bolt is 45” in width, then halve the fabric lengthwise to make two rectangles sized 22.5”x90”; if your bolt is 60” in width, then halve it to make two rectangles sized 30”x90”.
3. Fold and iron the edges of both long sides and one short side of each cloth. This is to prepare the hem of your cloth. Fold the edge of the cloth by less than a centimeter then iron flat. Then, re-fold the edge by less than a centimeter again, and then iron flat.
4. Pin the three folded edges on each piece of cloth and then sew them. Pin the edges that you have ironed flat, so that you may easily sew them. This is the final part of hemming your cloth. You can do this by hand or with a sewing machine. We used the latter, given to us by Kathy May’s mom. We opted for a zig-zag stitch rather than a straight stitch so that it could stretch with the fabric!
5. Join your cloths by creating a flat-felled seam between the two short un-hemmed sides. A flat-felled seam is a strong and durable seam, ideal for our wrap which would endure the stress of supporting a dog and frequent machine washes. It also encases both raw edges for a clean finish. Finally, it is completely flat for our comfort and Mimi’s.
Here is a cross-section schematic of what the flat-felled seam is:
This short and easy-to-follow video taught us how to create this professional-looking seam.
6. Wrap your dog! There are a number of ways to wrap your dog (or baby) on your chest or on your back, but we have found the easiest is the method recommended by the popular Moby Wrap and Boba Wrap. See our quick how-to video, featuring the one-and-only Mimi! Music credit: “The Printed Word” by David Hilowitz.
As you can see, the doggie wrap is essentially a very long piece of cloth with finished edges! We spent just a few dollars on this project with the purchase of the fabric, rather than spending $50+ on a designer baby wrap! Our doggie wrap can be folded and stashed into our bag, or tied around our waist, only to be whipped out when Mimi starts to tire. From the first use, she loves the doggie wrap! As you can see from the video, she jumps up happily to be placed into the wrap and enjoys being carried. Once she’s inside, she relaxes and enjoys the scenery. We hope that you make one of these adorable and pragmatic wraps for your pup (or maybe your baby)! Let us know what you think in the comments below!
Until next time,

Mimi is a happy, peppy pup and the theme we chose was equally fun and playful. For the basics of the main design elements, we used pre-made vector files of a simple house from clker and anthromorphized flowers from freepik. There are innumerable free vectors available online, and a large advantage of vector art is that they can be imported into Adobe Illustrator to save a great deal of time in the design stage.
That being said, there was still a great deal of legwork to be done to modify the vector art into Mimi’s design (don’t worry, we won’t go into the nitty gritty in this post). In addition to tweaking the vector art, we also added other details including Mimi’s name to customize the design. After finalizing the design, we prepared the Illustrator file for the laser cutter. The instructions for the laser cutter – engrave, line, cut, etc. – are communicated via color. In this image, for example, cyan commands “vector cut”; navy blue commands “vector line”; and black, royal blue, and red command variable depths of “engrave.”
Next, we were off to Boston Makers, the non-profit makerspace in Jamaica Plains where we volunteer! Its laser cutter, 3D printers, and more are open to the community – let us know if you’re interested in dropping by! We imported our Adobe Illustrator file into Corel DRAW, which is the program the laser cutter utilizes to translate color (as above) to command. We selected 1/4” birch plywood for Mimi’s door. Here are a couple of 30-second videos of the laser cutter at work:
After cutting and engraving, we sanded the door to remove smoke stains from the laser cutting process. To prepare it for the outdoors, we sprayed it with two coats of Thompson’s WaterSeal Waterproofing Wood Protector. While at Boston Makers, we devised a way to mount Mimi’s door onto the balcony. Our solution was to design and 3D-print two C-hooks that would clamp the door to the bottom horizontal rung of the balcony. Here is a clip of the LulzBot as it is 3D-printing our C-hooks:
Back at home, we cut a Mimi-sized peephole from the wind barrier panel and slid the top of the house under the barrier’s fastener. The bottom of the house is held in place with the 3D-printed C-hooks. Here’s the final construction!
Mimi loves her new doggie door! She is again able to enjoy her view of the city below and to get a nice whiff of fresh air at her leisure! Click on the gallery images below to see some snapshots of her enjoying the balcony. By the way, we loved her door so much that we laser-cut a second copy to paint and display indoors. A picture of that is included in the gallery too!
Until next time,

This first charm is intended to represent Kathy May’s time training at the Massachusetts General Hospital, which is the original and largest teaching hospital of Harvard Medical School. The design of the charm is inspired by the logo of MGH as well as that of Harvard. Because of the small size of the charm and the physical limitations of the 3D printing process, the details of the logos had to be stylized somewhat, but not too much that the logos were no longer recognizable. I also wanted to take advantage of having the third dimension to work with and make the charm more than just an extruded 2D shape. I thus took the graphical part of the logo, which represents the Ether Dome of the Bullfinch building, modeled it in 3D, and put it on the top of the charm like a roof. The Ether Dome is an architectural landmark on the MGH campus, but is also historically significant as the location of the first successful demonstration of surgical anesthesia in 1846. Before this, all surgery was done fully awake, if you can even imagine what that would have been like! Watch the video below for a look at the design and preparation stage of the creation of this charm:
A digital 3D model of an object is needed to instruct the 3D printer how to make the object. I used Autodesk’s 123D Design to create the model. This program was free but unfortunately has been discontinued by Autodesk in favour of its other 3D modeling programs, TinkerCAD and Fusion 360, which are both free for personal use. The basic principles of the programs should be similar, though. 123D Design has a point-and-click interface that has a live rendering of the model, and it accepts keyboard input for more precise measurements. You start with primitive solids such as cubes and cylinders as well as with 2D shapes such as curves and text that are extruded or otherwise made into 3D solids. These are then combined and subtracted to create the final, complex model. The 2D drawing and text tools are adequate for many things but it’s also possible to import SVG (Scalable Vector Graphic) files from more sophisticated software such as Adobe Illustrator or the free/open-source Inkscape.
For this charm I used Illustrator to extract the shape of the shield from a file of the MGH logo. I also prepared the text with Illustrator to make use of fonts and typography tools not available in 123D Design. These were saved as SVG files and imported into 123D Design. There is a problem with small SVG files being distorted when imported (it may be some kind of rounding bug) so to get around it, create the file with larger dimensions and scale it back down after importing. I transformed these 2D images plus some simple 2D shapes drawn directly in 123D Design into the model of the charm using the extrude, shell, revolve, combine, and align tools. For a necklace charm, it is also important to position the opening for the chain so that the charm is weighted properly to stay upright when worn. To do this, I divided the charm into a top and bottom half, and measured the volume of the halves to ensure that the bottom half will be heavier than the top. Finally, I engraved some simple lettering into the inside of the charm. Watch the video below to see how I created the 3D model in 123D Design. The screen capture runs at 4x speed to save time:
This is a longer, more detailed version where the screen capture runs at 1x speed if you are interested in learning the process step by step (note: the video runs about 30 minutes):
Although the makerspace where we volunteer, Boston Makers, has several 3D printers, printing in metal is beyond the capability of a household desktop 3D printer since the melting point of metal is so much higher than that of plastic. I used Shapeways’ industrial-grade equipment to print the charm in sterling silver. Shapeways is a 3D-printing service that takes the digital 3D model and prints it in any of a variety of materials. They also offer a marketplace where artists can sell their work, which is printed on demand and shipped directly to the customer. Other similar services include i.Materialise and Sculpteo. These services make 3D printing of finished products available to anyone with a digital 3D model. In this case I exported the model from 123D Design as an STL (STereoLithography) file and uploaded it to Shapeways.
There are several techniques for printing metal. For precious metals such as silver and gold, Shapeways uses a lost-wax casting technique. The object is first 3D printed in wax. Then, liquid plaster is poured into a container around the wax object to create a mold. After the plaster sets, the wax is melted out and molten metal is poured into the mold and the mold is removed from the object. Finally, the object is polished and shipped. The whole process took about ten days from upload to delivery. Did you know: metal Pandora charms are also made with a lost-wax casting technique – though the wax models are made using rubber molds rather than being 3D printed. Here is another photo of the final charm in sterling silver:
[See image gallery at www.kathymayandsilas.com] Although consumer-grade 3D printing was overhyped a few years ago, 3D printing is a technology that is unquestionably going to be increasingly important in the future. One of the things that 3D printing is perfect for is individualized, custom objects like Kathy May’s charm. The technology makes it possible for anyone to create a unique object at a reasonable price in a reasonable timeframe. If you want to see what other people have been doing with 3D design and 3D printing before designing something yourself, Thingiverse is a great place to look at other people’s designs, which you can download and print yourself. Have you designed and 3D-printed anything interesting recently? Do you have suggestions for improving the creation process? Leave us a comment and let us know!

[See image gallery at www.kathymayandsilas.com] ]]>Years ago, my mom taught me how to make these paper flowers (click here to see some examples), and they have become one of my most favorite projects. My mom herself learned and perfected the technique so that she could make a bouquet for me and a boutonniere for Silas. Now it is my pleasure to share this paper-craft with you. My mom and I developed a number of variations for the paper flowers, which I will share in future posts. In this post, we’ll begin making a basic petal design. In the next post, we’ll assemble the petals into a complete flower.
Step #1: Gather your materials.
Step #2: Cut a square of paper. A typical paperback novel is the perfect size. If you cut a square out of a page, save the rest of the page for Part 2 of this project.
Step #3: Fold the square in half diagonally. Place the open side towards the top. Your folded paper should look like a triangle with the longest side on the bottom.
Step #4: Fold the right corner of the triangle to the center corner.
Repeat for the other side. Then place the open side towards the top. Your folded paper should now look like two triangles with their long sides touching, and the two triangles overlying a square.
Step #5: Fold down the long side of the right triangle to meet the short side of the triangle.
Repeat for the other side. Your folded paper should now look like a kite with two triangles emerging from the sides.
Step #6: Trim both side triangles to make them flush with the square underneath. Your folded paper should now look like a square that is made of a kite and two triangles. Position the triangles towards the bottom and the kite upright.
Step #7: Place glue along the bottom two sides of the square. Then lift the triangles and place glue along the bottom two sides of the square under the flaps of the triangle. Place the flaps of the triangles back down.
Step #8: Fold but do not crease the square vertically along the diagonal of the square. Make sure that you bring the faces of the two triangles together. Once again, make sure you do not crease along the fold.
Step #9: Secure the glued edges with a clip. Wait until the glue is dried, then remove the clip. Depending on the weight and quality of your paper, this should take just a few minutes.
Congratulations: This is one petal! Repeat the above process so that you have around five to seven petals. Then, wait for Part 2 of this series, when we will finish our paper flower!
Until next time,
Kathy May and Silas

To start our project, Kathy Mây sketched the design. We decided to go with a clean image, one that was bold enough to reflect the confidence and showmanship that is typical of the Rooster.
Silas scanned the sketch into the computer. He used Illustrator to trace it and then clean it up into a final vector drawing that can be understood by the laser cutter. He then added trilingual text and a simple East-Southeast-Asian inspired design that did not overwhelm the Rooster, who thrives upon being the center of attention. In the Illustrator file, different colors corresponding to different laser settings.
We used the laser cutter at Boston Makers to complete our project! Based in Jamaica Plain, Boston Makers is a nonprofit organization that provides a collaborative workspace to encourage creativity and engage the maker spirit in the community – young and old, gals and guys, novices and experienced makers of all kinds! We have been volunteering there as hosts to staff the space and help people use the equipment to create their projects. If you are interested in learning or pursuing 3D printing, soldering and electronics, textiles and fabric arts, woodworking, arts and crafts, or any other kind of project, please let us know in the comments below!
We decided to use regular red posterboard, knowing that only the outside paper was dyed red; the internal layers are uncolored paper that would show up as a light brown. On the laser cutter, we used both the engraving and cutting functions. Click on the short video below to see the process in action:
Each rooster card was 65 x 95 mm, the perfect size to fit in a red envelope.
Here is the card evolving through its stages of creation, from sketch to vector art, to finished product!
In addition to the Rooster card, each red envelope also contained our annual picture – in color coordination, of course – to commemorate the Lunar New Year.
Happy Lunar New Year! This year we wish you peace, happiness, good health, and anything your heart desires!
Chúc mừng năm mới! Năm này mình chúc bạn bình an, hạnh phúc, sức khỏe, và vạn sự như ý!
新年快樂! 恭禧發財!

This year, we were thrilled to explore Maker Faire with Jon, Lily, and Jen! We chatted with creative minds of all ages and sizes and types. We learned about the latest machines, gadgets, and doodads. We heard about projects that others are pursuing and picked up ideas and tips for our own. We even made some things right then and there during the faire. Most of all, we had lots of fun!
This is the first year we’ve participated in one of the most popular Maker Faire activities: learning to solder. Donned with Google safety glasses, we soldered a battery holder, pin, and LED to a printed circuit board in the shape of the Makey Robot. So easy and fun!
In the Maker Shed, we saw a vast array of innovative projects. One of our favorites was the circuits-in-a-bottle project by Kimio Kosaka. Incredibly, all the parts are soldered together inside the bottle. Unfortunately, this picture does not do this creative project justice! We were too busy marveling and asking questions. See more details on Kimio’s DIY video!
Maker projects spanned from fun at-home endeavors to commercial ventures. For example, we loved the MATRIX Creator, which is basically a Raspberry Pi add-on pre-built with a number of sensors and microcontrollers, powered by a proprietary (secret algorithm) operating system. Its capabilities are endless and clearly largely unexplored! Watch our video below to see one potential functionality: Face detection, tracking, and interpretation (also featured: our silly facial expressions :-P).
We tried our hand at single-pin lock picking. The instructions are much more easily explained than executed. Of our group, only Lily was successful! Here she is “supervising” Silas and Jon sweating away, hard at work.
Years ago, at our first Maker Faire, we saw our first 3D printer. In a shockingly short amount of time, after decades of utility in industrial fabrication, these have now become mainstream. The MakerBot Replicator and even Formlabs Forms are old news and companies are now striving to distinguish themselves. Nowadays, you can 3D print plastics, metals, clay, rubber, even chocolates. We saw many examples of great efforts: printers which used plastic waste instead of filament or resin, others which printed and mixed different colored plastic, etc. We were most impressed by the ONO, the first-ever smartphone 3D printer which raised over $1 million on Kickstarter in just 5 days! A tray filled with DLP resin sits over the smartphone. This resin hardens with exposure to normal visible light. An app displays patterns on the screen to harden the resin while a moving platform pulls the hardened resin up so that the next layer can be printed. It should be available in the U.S. soon!
Check out this Knitting Printer, an awesome invention brought to us by Asbjørn Rørvik and Fredrik Fjellså from Norway! We were entranced by the process. So far it looks like its functionality is limited to making tubes – socks, scarves, and Dachshund sweaters… but who can have enough of those?! By the way, the component parts of these automated knitting machine were 3D printed, too!
Here are some other pictures of our highlights during the day!
1. Jon listening to knitting. Teresa Lamb wears a harness and arm-piece which translates the movements of knitting into sound.
2. Lily jamming out on a ukelele programmed with Arduino.
3. Kathy May operating Shaper Origin, the world’s first handheld CNC machine. It’s totally portable and self-guiding!
4. Silas examining water bears AKA tardigrades (indestructible micro-animals that can survive in outer space) under the microscope.

Now that you have made a large pile of triangular component pieces (see “Part 1: Fold the Component Pieces“), we can start to build a ring base! A ring base is a versatile foundation for any 3D origami creation. On the left is a ring base alone; on the right is a ring base as the foundation of a 3D origami swan.
In this tutorial, we will make a ring base of 30 component pieces. Please note that you may alter the number of component pieces in your ring base to make larger or smaller 3D origami creations. Shall we begin?
1. First, make sure you have a sufficient number of component pieces. For a ring base of 30, you will require 60 component pieces for the base itself. Of course, you should make extra for the rest of your origami sculpture.
2. Note that each component piece is a right triangle. One leg of the right triangle has two “pockets” (red arrows) while the other leg has two “wings” (blue arrows).
3. Insert the left wing of one component piece (B) into the right pocket of another component piece (A). Make sure that the component pieces are facing the same direction (i.e., that the right triangle component pieces are parallel).
4. Then insert the right wing of a new component piece (C) into the other pocket (A).
Here’s what your 3-component-piece unit should look like from the front and back, front and side.
5. Repeat Steps 3 and 4 with new component pieces until you have 15 sets of 3-component-piece units.
6. Hold 2 sets of your 3-component-piece units (E & F) side-by-side. Take a new component piece (D) to join these 2 sets together. The right-most wing of E should go into the left pocket of D; the left-most wing of F should go into the right pocket of D.
Now you have created a 7-component-piece unit. Here’s what it should look like from the front and back.
7. Repeat Step 5 until you have 7 sets of 7-component-piece units. Since we have an odd number, the 8th set will be a 3-component-piece-unit, which I’m holding in the picture.
8. Hold 2 sets of 7-component-piece units side-by-side. Take a new single component piece to join these 2 units together. This is analagous to the previous step – you’ve got the hang of it! We are assembling these in smaller units because assembling a long chain becomes unwieldy!
9. Continue joining sets until you’ve made a semicircle. Make this a complete circle by using your final single component piece to join together the wings on either side of the semicircle.
10. There you have it – you’re done! You’ve made a ring base of 30. It should feel sturdy at this point, not requiring glue. You can tighten it (but not too much, please) by pushing the outer layer into the inner layer of component pieces. As we add more layers later, the structure will be further strengthened. Here is a view of the top and bottom of your completed ring base.
The entire process of modular origami is very simple once you have learned the basics. Here are a couple of images to help with troubleshooting. If you have any questions, please leave me a comment below and I’ll be happy to help!
Troubleshooting #1: Make sure that the correct wing of your component piece goes into the correct pocket of another component piece.
Troubleshooting #2: Make sure that all of your component pieces are facing the same direction (i.e., all hypotenuses of all component pieces should be parallel).
Congratulations on making your 3D origami ring base. Hopefully you made many more than 60 component pieces so that we can go onto Part 3. Stay tuned – happy folding!
Until next time,
Kathy May and Silas
In preparation of making our pysanky, we required a number of specialized equipment. Even though pysanka-making kits are available, we opted to pick and choose our supplies. We bought them at an authentic Ukrainian shop in Lower East Side, Manhattan (Arka on 2nd St at 1st Ave). Here’s what we got:
In addition to the more specialized supplies above, you will also require a number of household supplies:
Other items you may consider using are rubber bands and flexible rulers made of paper or cloth to help you make straight lines in planning your design. You may also choose to have gloves and newspapers handy because of inevitable messes. Finally, cotton balls may be helpful to apply color to a small section without submerging the entire egg.
In the next post of our pysanka series, we will begin our pysanky by preparing the eggs and mixing the dyes! Stay tuned.
Until next time,
Kathy May and Silas
]]>Last time Silas and I were in San Francisco, we visited the SF Cable Car Museum and learned that the famous SF system is the only one that still operates entirely manually. Three of the 23 original lines established in the late 1800s comprise the current SF system. Other than in SF, we’ve only ridden cable cars in a few other cities including Las Vegas and Toronto. Like the SF cable cars, these run alongside street traffic; however, these are not traditional – they are fully automated, allowed the right of way, and not intended for mass transit (though admittedly even in SF cable cars are more for tourists than commuters nowadays). In general, the popularity of cable cars never became widespread because of the introduction of electric streetcars soonafter. In SF, their persistence and survival may be attributed their mechanism of traction locomotion. Notoriously steep areas of the city were more conducive to cable car than electric streetcar. Now SF cable cars are listed in the National Register of Historic Places.
The eleven pieces of the SF cable car model from Lily were contained completely on a single sheet of steel. For assembly, we decided to wear latex gloves to minimize fingerprints, especially on the inside of the cable car which would be inaccessible in the final product. Each component piece of the model was supported at two or three points within the metal sheet. They popped out easily with little effort.
The instructions were entirely pictorial and easy to follow. Some pieces required folding along fine scores in the metal; others required bending. The pieces fit together seamlessly by a simple tab system. If a piece had a tab, the corresponding receiving piece had a slot for the tab. After positioning the pieces together, the tab was then twisted or folded to keep the pieces together. We used our fingers or needle-nosed pliers for assistance.
Here is the finished San Francisco cable car! The entire 3D model is approximately 2” x 1” x 1”. You can see the intricacy of the detailing on each piece, thanks to the laser-cutting technique. These details were even more beautiful given the small scale.
Thanks, Lily, for your thoughtful gift and for an afternoon of fun!
Until next time,
Kathy May and Silas
The Eastern European tradition of creating pysanky (singular pysanka) is generations old with historical and religious undertones. Amazingly, these impressively intricate and magnificently ornate pieces of folk art are created by dyeing the egg, not by painting. Obviously, pysanky takes your typical childhood Easter egg dyeing session to the next level… This Easter season, we made our own versions with our friends Anjie and Lily!
Pysanky are created using a wax-resist method. Essentially, eggs are sequentially dyed in progressively deepening hues. Between each dye, a design of wax is applied to retain that particular color and prevent it from being removed by the next dye. At the end, the wax is melted to reveal the vivid colors of the previous dyes. The project requires a good deal of planning, precision, and patience but the final product is extraordinary.
Additionally, the project requires a number of specialized supplies, which we gathered from an authentic Ukrainian shop here in New York City (Arka on 2nd St at 1st Ave), as well as an assortment of household items. Once we prepared everything we needed, we proceeded to experiment with pysanky with Anjie and Lily. Here are our buddies hard at work! Anjie made a beautiful abstract geometric and floral pysanka. Lily made an innovative Star Wars-themed Boba Fett pysanka.
We’ll post a detailed “how-to” in our blog in the near future which will elaborate upon the tools and procedure of pysanky but, in the meantime, this is an overview of what we did:
We had so much fun! Every person designed their own egg, and we used a combination of traditional pysanky motifs and modern-day imagery. Every person also planned their own sequence of dyes, and the results were excellent. The most exciting part of the entire process is melting the beeswax. Prior to this step, the egg looks particularly unpleasant because of ugly blobs of wax – the designs and patterns are not even clear. When the wax is melted, it easily wipes away, revealing colors much more vivid than expected.
Below, view a gallery of our beginner pysanky creations! We were very satisfied with the final results and this is a craft that we will definitely continue – whether or not it is Easter! Stay tuned for more details on our “How-To” of pysanky, and watch our creations progress at we get more practice…
Update: Click here to see “Part 2 – Materials list for making Ukrainian Easter eggs” in which we go over the tools and materials needed for this traditional craft.
