I have a necklace that my dad and I made together at the beginning of last year. It's a choker made from used gun shell casings of various sizes arranged in a design reminiscent of an Egyptian collar strung on black satin ribbon. My dad collected the shells, polished them, and joined the metal bits together. I collected the jewelry bits and did the design. I wear it when I need a boost in confidence, and it usually works (although that might be from the fact that anyone seems more confident when the people around them are freaked out by someone wearing bullets...)
