Before you fill the pot with gold, build the leprechaun. Start with the torso. Roll a large oval shape with green Model Magic to shape the torso. Stick it inside the center of the pot. Roll out 2 small, medium length pieces of green for arms. Make two small triangular shapes on for a collar. In the center, place a small, flattened oval shape for the leprechaun’s shirt. Roll out tiny balls for buttons. Roll out two small balls for hands. Flatten them slightly. Use a clay tool or plastic knife to create a thumb. Add to the ends of the arms.
