Using the turquoise blue/green pennies I enameled, some 14 gauge copper wire and a wonderful copper toggle clasp, I created a charm bracelet of sorts.
Once I photographed it, though, I thought it looked too, well, copper. I decided it needed some patina (I use Perma Blu gun bluing), so I dunked it and rubbed it to show some highlights and like it so much more now.
For this bracelet, I used (again) some pennies that I drilled and domed; some 16 gauge copper wire and again a beautiful copper toggle clasp.
