I liked this idea so much that I had to make two.
I made these using meltable beads. I got them years ago and can’t even remember the name, so unfortunately I can’t say where you can get them. I originally got them from Walmart in a sun catcher kit. I put the beads in glass monkey bowls and melted them for about 20 minutes at 450°. When they came out I let them cool, twisted them to get them out and then drilled holes in them for hangers. They catch the light so well, I love them!
I think the purple/blue one is my favorite, though I like the red/green one too. I used some glow in the dark beads around the edges of the red/green one and it looks kinda nifty.
