Design it so it is structurally sound with the clay. Tiny cartoon legs cannot support the weight of real clay !! . Style it after a person, an animal, or a cartoon character.
what you need:
you will need a pop can & a plastic shopping bag. You will also need 2 sketches of your ideas. Make sure you draw 2 different things (one cartoon and one animal or human). Plan to have the head as the removable lid.
