1. Pick out the ultra-light clay whose color is close to that of moon cakes, then rub it into a ball and flatten it slightly with a plastic plate.

2. Then use a knife to evenly carve scratches on the side of the ultra-light mud, so that the shape of the ultra-light mud is closer to the moon cake.

3. Finally, take some ultra-light clay and knead it into thin strips or balls as patterns and decorations for moon cakes.
