Old light bulbs, got at a flea market, again drill a hole and I'll make anything into jewelry! I think I actually made these in Jan of 2022 but I've made them before.
I added words, crystals and chain. I would love to make necklaces with old light bulbs, but they can be so fragile I mostly haven't. Making the older, thicker glass ones into earrings is pretty safe, they aren't as likely to be abused.
