Sculpt your media of choice into a sphere. Whether using paper mache, clay or harder materials, work the surface into a balanced, spherical shape.
Make indentations on the surface of your sphere. With clay or softer media, press into the sphere to create small craters. For harder surfaces, remove small areas of the surface to make craters and indentations.
Mix orange and red paint to create a bright hue. Apply this color to entire surface of the sculpture.
Apply pure red paint to a few areas of the sphere. Use a clean brush to blend the edges of the pure red into the orange-red hue. The color variation helps create visual interest.
Fix your sculpture to its base or hanger.
