Copper wavy circles and "scrap links". Scrap links are just that: I take some of my scrap copper....cut various shapes...then stack & solder a couple/few/several of the shapes together. Each one is then hammered/textured/shaped, with any sharp edges sanded smooth. I never quite know what I'll end up with till it's done...but that's the fun part, turning those scrap links into an interesting piece of wearable art....in this case a bracelet.
Total bracelet length is 8 to 8 1/2", lobster clasp, flame patina. Circle link diameter is 1", scrap links are about half that.
