The choice of covering can be determined during or after the design process is complete. If a character design looks fuzzy, fluffy, bushy, and plush, then there is a good chance that it will be covered with fur. When patterning a fabric covering such as fur, the first impulse might be to use the foam pattern used to make the foam object; however the goal when using fur and any fabric covering is to keep seams to a minimum. Faux fur is a fibrous material available in various thicknesses that has a fabric foundation. Fake fur is made of plastic fibers and as far as changing the color is concerned, it is much better to buy it pre-dyed. In the past it was only possible to dye fur using acetate or nylon or polyester dye, steaming water, a respirator, goggles, gloves, and patience and if the foundation color of the fur was white, brilliant custom colors could be achieved.
