Plastic Canvas Icosahedron

January 18, 2009 at 10:12 pm 15 comments

It isn’t unusual around Christmas time that I do some sketches, get out some graph paper and work on a Plastic Canvas project for someone on my list. Usually my patterns are in the form of cartoon characters (such as Beavis or Cartman) or Hokie Birds. This year, I did something a little different for the science geek on my list. I made a plastic canvas icosahedron. It’s not a cartoon character, but it did have a solid role in the Futurama: Bender’s Game movie!

An icosahedron is a 20-sided platonic solid. In the regular icosahedron, each face is an equilateral triangle. Icosahedrons are everywhere. If you shake a Magic Eight ball, your fortune is being reported back to you by an icosahedron. Like Scattergories or role playing games? The die you play with is an icosahedron. Do you have herpes? Well then, my friend, you are infected with microscopic icosahedrons!

And as if herpes and Magic Eight Balls are not treasure enough, you can now have your very own icosahedron constructed out of plastic canvas!

It was actually one of the more simple stitching projects I have taken on. The steps are quite easy:

Plastic Canvas Icosahedron - Original Hexagon Plastic Canvas 1) At Michael’s, I purchased some nifty hexagon shaped sheets of plastic canvas. They are also available online at Everything Plastic Canvas. You’ll need four hexagons for this project.
Plastic Canvas Icosahedron - Six Equilateral Triangles 2) I cut each hexagon into six equilateral triangles. That gave me 24 rectangles– 20 for my solid and 4 extra.
Plastic Canvas Icosahedron - Single Triangle 3) Stitch each triangle to your preference. I just used a simple backstitch using decreasing shades of purple and a black center.
Plastic Canvas Icosahedron - Sewing the Pieces Together 4) Start stitching the triangles together. I found it much easier to put the pieces back to back as long as I could (That gets more difficult as our solid takes shape). I used a standard overcast stitch. I typically did two stitches in each hole, with extra stitches at the triangle points for additional support.
Plastic Canvas Icosahedron - Five Piece Cap 5) With the assembly strategy, I first stitched five of the triangles together to create a little cap.
Plastic Canvas Icosahedron - Adding Triangles to Original Five Piece Cap 6) Next, I stitched an upside down triangle to the bottom of each triangle in the cap.
Plastic Canvas Icosahedron - Adding Triangles Between the Triangles 7) Between each of those newly attached upside down triangles, I stitched a right-side up triangle. After that endeavor, there were 15 pieces sewn together.
Plastic Canvas Icosahedron - One Five Piece Section, One Fifteen Piece Section 8] I set aside my work so far and stitched another five piece cap. Now I had two sections– a 15 piece section and a small 5 piece cap.
Plastic Canvas Icosahedron - Done! 9) Finally– I stitched my two sections together and viola — Plastic Canvas Icosahedron.

Additional Icosahedron Projects

Now say you covet your very own icosahedron, but you don’t want to work with plastic canvas and you don’t really want herpes. You can make icosahedrons with just about any arts and craft technique and out of a variety of materials– even marshmallows! Here’s a quick collection of links to help guide you on your icosahedron whims:

    Oh wow. Thank you very much for the step by step instructions. I’ve been wanting to make a 20 sided die with plastic canvas for the longest time, but I didn’t know how. This tutorial with pictures =D make this project doable and fun for a beginner like me.

    Well, this isn’t exactly a necropost but since I stumbled upon your icosahedron thread, I thought I’d share/self promote something I made for my etsy shop. It’s a 20 sided die that takes the form of a box.

    Also, I love all the links to other projects out there. That crochet die is pretty amazing.
