I’ve tried this several times in the past and never succeeded. This time I used a different technique and heavier wire.
These are electroplated quartz crystals drilled and purchased on a strand. Not too expensive and so perfect for trial and error. I chose a 16 gauge black annealed steel wire and pulled it through xxx steel wool before preceding. The crystals are tough and not so easily chipped or broken so I was able to use parallel clamping jaw pliers to hold the parts while I wrapped. Haha, fun! Maybe I’ll put these in leather thongs.
