I havn't tried it recently,used to paint eyes on them using vinyl paint many years ago. They probably would look better since my painting skills have improved a little since then.I don't have any right now,just the bead chains.Those may work as well.
I have tried the bead chain, but the beads swivel around so much that I didn't like it. I was just thinking some of the nice colors I can get from using powder paint, that they would look better than the commercially-available ones.
The only problem with powder paiting them is holding them while heating and hanging them to dty or cure.I tried powder painting some slip sinkers and what a hastle that turned out to be,lol.
