A variation on the age-old nature necklace, these wire-wrapped pendants are fun for kids to trade. Some girls paint their names on one side and their best friend's on the other, and wear them as a proclamation of their unbreakable bond.
Place the rock at the center of a 15-inch-long piece of wire and wrap the wire around the rock a few times to secure it.
Twist together the ends, then wrap the twist around a pencil to form a loop. Use pliers to close the loop, then cut off any excess wire.
To finish, thread a necklace-length piece of leather cord through the loop and knot the ends.
