1. Cut out dinosaur body.
2. Cut the line between the legs and along the belly line. Roll the leg flaps up toward each leg. A tight roll should stay in place, but use glue or a bit of tape if needed to keep the leg roll together.
3. Fold body halves together. Sharply fold the top of the sail, but put a mild crease (about 15 degrees) at the base of the sail on both sides. This makes a straight up and down sail and an A-frame like body. Glue sides of head and tail together.
4. Add volume to the body with creases at shoulder and hip.
