I think these are called rotating ring flexagons... it seems an appropriate name, anyways. I made one out of paper a long time ago and thought it was really fun to play with, but I was always worried about breaking it by using it too much. I thought it would be interesting to make a sort of more organic and cuddly one out of fabric, and see if the rotating mechanism would translate well into that medium.

It came out pretty well! If you want to make one yourself, you will need:
  • Four types of fabric
  • Fabric scissors
  • Batting
  • Sewing machine
  • Sewing supplies (needle, thread, pins, marking pen)

Step 1: Create Your Templates and Cut Out the Pieces

You'll need three identical templates (you can reuse one if you don't need to worry about arranging them on your fabric). You want the end product to be composed of pairs of isosceles triangles, joined at the base to form diamonds. The triangles I made were 75mm along the base, and 85mm along each leg. You can do any size you'd like, as long as you maintain the correct proportions. I was limited by my small fabric samples.

Use the templates to cut out three diamonds from each type of fabric. Make sure to leave ample borders, you can always trim later. You need 12 diamonds total.

*Note* My end product was a tiny bit 'loose' to my taste - the sides could have pressed together more tightly. It might be a good idea to go with more nearly-equilateral triangles for the template, to fatten them up and bring everything a bit closer. The exact measurements here are based on the rigid paper version.
Do you know any book about flexagons (how can you make some flexagon)?
It is great! I didn't make it yet but i am about to
It was really great!
i think this is fantastic! i think i might try sewing a bigger one and put it on a couch :D
could you make the diamond pattern available here?
Flexagons rule! :D <br> <br>Have you seen Vi Hart's stuff on Youtube? If you like flexagons you're in for a treat...
Yeah! I met her at a juggling convention once, she's awesome. I'm nowhere near as successful, but I actually make science videos on youtube as well.
This will be a great gift for my nephew... I'm sure he will love it!
Awesome job!
