I've done a fair amount of beadwork. Some of it is perfectly traditional work; peyote stitch bottles and the like. But most of it is geometrically based, using glass bugles and fishing line to produce polyhedra.
Here are two different views of the same, relatively simple object;
this is a straightforward stellated dodecahedron. (Note: If you believe
that "stellated" means "with points stuck to it", you have been misinformed.
Probably, like me, by a geometry teacher who ought to have known better.
A stellated polyhedron is one whose faces have been extended until they
reintersect. There are multiple stellations of the dodecahedron, and this
one happens not to be pointy.)

Not all of my constructions are that geometrically pure. Here are two
views of an object with no simple geometrical description.

Not all of them are that complex either. Here's a whole pile of simple
ones, beaded beads in the form of dodecahedra, and a moebius strip
bracelet.
