How-To: Knit or Crochet a Dodecahedron

This week’s Math Monday over on MAKE had an awesome crafty bent.

If you knit, here’s a stuffed, dodecahedral thing–I don’t know quite what to call it–a toy, a pillow, a mathematical model? The shape is based on twelve 5-sided units like a dodecahedron. But they bump out, so the form is more like a small stellated dodecahedron. This was designed by Norah Gaughan, who provides instructions in this Berroco pattern.
