Step 2: Shape the Star. Cut the flattened clay into a basic five-point star shape using a craft knife. Consequently, use your fingertips to smooth the edges. you eliminate any sharp, unrealistic lines from your creature.

Step 3: Add Organic Texture. Take a blunt wooden tool or a large needle. Then, gently press tiny dots across the top surface of the clay star. real starfish have rough skin, this step creates incredible organic realism.
