Have you seen the new Beads 2009 Magazine? I love the overview they give - all kinds of different beads, from art beads to czech, to whatever! If you noticed the magazine, you may have noticed there's a key bead on the front cover - not mine, of course, but a key bead nonetheless. I think these are very cool things to use in your jewelry. As pendants, for sure. Are there other uses? I'm sure someone is going to come up with one. I can think of using it on your key ring, or on your purse as a decoration. Can you think of others? I know I enjoy making them!
