Wool, cotton, sisal, abaca, jute, linen and silk are some of the natural fibers used in the making of carpets and rugs.  Of all the fibers, including synthetic, wool is considered the standard by which others are measured. It is a sustainable fiber that is highly regarded for its strength, durability, crush resistance, easy maintenance, and comfort.  Karastan manufacturers its wool styles using the finest New Zealand wool in the making of its products and maintains exceptional quality by processing, dyeing, and weaving its wool in-house.
