Hi Kristina, have you tried making them yourself? my DH cuts down antlers, a friend uses cleaned roast bones, polymer clay is easy, colorful and quick. i saw some at the fiber festival this past weekend made from tree branches cut to width and then polished or not as the mood hit. good luck with your search.
Some dreams are worth the risk it takes to make them real.
Don't tell me the sky's the limit when there are footsteps on the moon.
Uh, I haven't even thought of that at this point. I did get in touch with the company that makes the ones I did find, and they may be able to get some more. I'm waiting for a reply, but they do not sell on-line. I am limited to supplies in my area, and bought the last two packets of buttons at JoAnn's that are a bit smaller than 8mm.
