A while ago i bought some pink plastic circle alphabet charms from johanns and now i found that i'm ending up with the letters that i never use like z, x, w, v, q etc. so what i did with the extra letters was i flipped it to the other side (its blank and looks just as good as the front but with out the letter) and used a rub-on. Its looks really great and you cant tell that its the backside at all :]
