This is my first attempt at making a copper cuff. Three different solder joints on top of each other and luckily they all held. The surface was textured then treated with liver of sulfur. The inside of the blank was lined with polymer clay since it fits snug to the wrist and green wrists just aren't my thing. Hope the polymer holds tight as the cuff needs to flex a bit each time it is worn. Next time, I will rough up the inside to give the polymer more tooth for adhesion.
