I enrolled in a jewelry making class over the weekend: Rivet Magic. The task was to make a pair of metal disk earrings. However, we had to cut out our own disks of metal, texture/hammer them, drill holes, and make a smooth rivet. Then, we could add any stones or gems that we wanted to add some interest...or bling. It took a couple of hours to do this, and the instruction was very good. Had blast!
