Create a necklace with Aboriginal style! Start by kneading a small amount of Crayola Terra Cotta Air-Dry Clay in your hands a few times to loosen it up and give it a smooth texture. Use the side of a colored pencil or marker to roll out the Air-Dry Clay on a clean, dry surface. It should be about as thick as a pencil when you are done. Press a round cookie-cutter or plastic cup firmly into the clay, forming the shape of the medallion. Store the remaining Air-Dry Clay in an airtight container for future use.
