The type of fiber used in a rug plays a key role in how it feels and how well it performs. There are two basic types of fiber, natural and human-made. The predominant natural rug fiber is wool. Other natural materials such as silk, linen, and cotton are sometimes blended with wool, but rarely used alone.
