Once we find a component that speaks to us, we tend to experiment with it, incorporating it into as many pieces as possible until we find an iteration that sticks. When we folded a pair of these 3-inch-long brass arrow charms into gently curving half-circles and attached them to thin gold-plated earwires, we knew we had a winner. It's one of those wear-it-many-ways designs: do you want the arrowhead or the fletching facing out? Maybe you want to wear one each way. With the earwires, the total circumference of each earring is about 4 1/2 inches. The brass charms will oxidize beautifully and unpredictably over time.
