Hi- I just discovered this site when I was looking for microbeads. Apparently the owner is a member hewre too. At any rate- it seems like it would be worth checking out. The pieces are already drilled. Here is link:
Pennywise Arts ~ Beadables & Other Products. Hopefully this worked. I am pretty new + not real sure of how to list a link.....Pennywisearts.com would get you there. Good luck. Let us know what you find and post some pictures of your projects- I would love to see them.
