CapsuleCorp: I just happened by your profile this evening and couldn't help but notice the earrings. Hobby Lobby? Is that a store? (I need lightweight metal for earrings myself for a pair of wild earrings and it sounds like what you used would be perfect.) ^^; Please PM me about that!
Actually, it IS metal. It's craft-weight tin from Hobby Lobby, cut to shape and etched to get the lines in. Didn't need special tools either.
It's really light, thank goodness. I don't think I could stand to have anything big and heavy (like sculpey) hanging from my ears.
