The characteristics of a wool's fiber determine its quality. Fiber diameter is the most significant factor. Wool has a variety of uses besides clothing, such as carpeting, blankets and insulation. Wool can also be blended with kevlar to make water-resistant body armor. The most common wool color is a creamy white, although other colors such as brown and black are seen as well.
