Today we designed a bracelet by using TopMod to extract a ring of irregular pentagons from the center of a Pentagonal Hexacontahedron wireframe (our "giraffe polyhedron" from Day 194). We made small and large versions. The large should fit over most hands and form a bangle bracelet. The small is for those of you with more lady-like hands. For those with larger hands like me, you can cut off a couple of rungs of the small version to make a C-shaped bracelet that is easy to put on and take off, and fits more snugly, as in this picture:
