I made a set of rune pendants out of stone-colored clay. I'm a big cheater, though, since I acquired a set of rune stamps a long time ago. I just pressed the stamps into the clay, poked holes in them, baked them, and used a sharpie to color them in. The jump rings are chainmaille rings from a bracelet my brother made.
Beautiful gothic cracked mirror charm made of Fimo clay and a CD - very detailed and precise!
