This toy is a fabulous math lesson for your young friends (or yourself) and is also--as I’ve learned--a nice stress toy for kids with ADD.
The hexaflexagon is knitted in one piece then seamed.
The pattern includes a photo tutorial on how to seam and fold the hexaflexagon.
The blog associated with the pattern and the pattern itself links to videos of hexaflexagons in action.
I can’t wait to see the modifications you make! Enjoy!
