I am so happy and honored to be participating in the emc team, Etsy Metal Clay, charm swap. If you don't already know, the emc team is a group of extremely talented etsy artists who specialize in working in metal clay. I was juried into the group last year. The artists lend support to one another by promoting our shops and also exchanging ideas, techniques and resources.
For the charm swap we were required to make 24 identical charms, 22 to exchange with the other artists, and 2 additional charms that will be made into bracelets that the group auctions off for charity. Honestly, the last bracelet that was made (a year ago) was incredible and really priceless. The charms had to be in metal clay, silver or you could use bronze, copper or a combination.
