I didn't see any that looked like the star one, but I think this one http://www.boondoggleman.com/prj_chainlink.htm
could be altered a tiny bit to work (or at least, to my liking) but I can't figure out how I would put the beads in the middle like the original picture has. (I have the same star beads, just a different color. They have a hole at the top point and a hole directly under it *duh* in the bottom indentation.)
Or the The Split Brick/Pony Bead could probably do the trick, but I'd rather have the bead in the middle. This one would probably look more like the one in the picture, but I think I like the chain one better. What do you think?
ALSO! I'm planning on putting this on a keyring that's star shaped... I have an idea how to attach it, but maybe you have a better idea?
