I've been making icicles for christmas. Lots of icicles. I keep changing up the color combo's and ran across this, so I made it into pandora beads for fun.
They're hard to photograph, I'm not very skilled with the whole good pictures of reduction glasses. They look like aurae beads.
Here you go
(each one has slightly more reduction from left to right), and for two hints
-bullseye
-Three types of glass used in each bead. (the dot colors don't matter)
