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.

If you prefer to crochet, here’s another variation by Betsy Myles, also for Berroco.
