I used the actual zipper pull from my jeans and fashioned the zipper part from sterling wire. I roller printed the copper sheet with fabric from my apron (actually the fabric that it's photographed on) and heat patina-ed it. It's riveted together with sterling rivets.Below is the other piece I made in the workshop. We learned how to 'spin set' a faceted gem in a tube. I soldered that tube onto brass sheet that I sawed a shape out of (it looked like a turtle!) The river rock already had a hole in it, I set it in place by pushing the prongs around it.
The class was very inspiring and I look forward to applying some of these techniques to PMC.
