ClayPaws® Clay must be kneaded, then formed into a patty before making a paw print. This process is made easier with the use of Circle Molds. The Circle Mold allows you to make a perfectly rounded patty, every time, without wasting clay. Each Circle Mold comes with a laminated folder, called a Patty Pad, that provides a smooth and clean surface to work on. Instructions for use are printed on the inside of each Patty Pad. Reusable!
