Flat woven carpets are given their color and pattern from the weft which is tightly intertwined with the warp. The Nomadic tribes in central Asia used this techniques to make their tents to protect themselves from the elements. In addition, they started to use kilims, (flat weave) carpets to cover their earthen floors. As Nomadic tribes started to spread across western Asia, they spread their weaving techniques. Kilim rugs are important for the identity and wealth of nomadic tribes-people. In their traditional setting Kilims are used as floor and wall coverings, horse-saddles, storage bags, bedding and cushion covers.
