METHOD: Draw the design with a pencil on the back of the shrink plastic and cut it out. It will shrink substantially, so make it fairly large. These cats were about 15 cm and shrank to 7 cm. Punch a hole for the jump ring slightly in from the edge. Draw the face with a Posca pen and let dry before putting the design in the oven, which should be heated to 175 degrees. Once the design has shrunk and you remove it from the oven, place a weight on top of it to prevent it from becoming wavy. Have a heavy book wrapped in foil ready, for example, and press the design with it for a moment. Then attach the jump rings and chain. Make a little mini yarn ball and glue the yarn end to prevent the ball from unravelling. Attach it to the jump ring and then attach that to the chain.
