Several coils can be rolled in colors selected by students. Gently press these coils on the ball to outline each one. Fill the space with different colored coils of Model Magic. Van Gogh loved to use yellow to express happiness and often added unexpected colors within others. For example, white, yellow, and orange swirls are incorporated into the blues, some very dark, of his sky. Encourage students to add bits of extra colors and leave them swirled in the coils. After the first layer is filled, add extra layers of coils on these objects until satisfied with the ornament.
