Here is a somewhat amateurish photo of a pair of earrings I made from copper wire, copper sheet, and a glass bead. I cut copper into squares, embossed them with a stamp, domed them on a doming block, and pierced them with a drill. The dangles were made from 18 ga copper wire. I balled the ends with a torch, and hammered them flat. The ear wires were handmade from 20 gauge copper wire.

The picture to the right is what I really wanted to show you. This is a closeup of one of the hammered and embossed squares of copper sheeting. Look at that patina! I acheived this using a liver of sulphur bath, sanding down the edges of the sheet to round then and expose the shiny red of the copper underneath, and then I tumbled them in a cheapie rock tumbler made for kids, with stainless steel shot and and a little water and dish soap for 2 hours or so.
How cool is that!
Check back again for more about how to use a tumbler and why you would want to.Cheers, Christine
