Sometimes you can choose how your cast looks. You can pick cool colors or patterns.

Casts come in two types. The first type is made of plaster of @Paris. You may have used this material for arts and crafts. Plaster of Paris is a heavy white powder. When it's mixed with water, it forms a thick paste that gets hard fast.

The second type is made of fiberglass. This is a plastic material. It can be shaped. Fiberglass casts come in lots of colors. These casts are lighter and stronger than plaster casts. That makes them easier to wear.
