Just in case you can't get Swarovski buttons out of your head since they were mentioned here recently, I have a link for you!
Fusion Beads has them all! Wow, I didn't expect to find them all in the same place.
Sometimes you see rivoli's OR a few of the round buttons, but this is a real find!
I don't think I have even SEEN this one before. It is described as:
3024 32mm Crystal Volcano Swarovski Elements Crystal Dufflecoat Button.
Wouldn't it be fun to work for Swarovski and come up with these names? You've gotta love it!
