Tribal rugs from the Zagros mountains of western and southwestern Iran, woven by nomadic, semi-nomadic and settled village weavers such as the Bakhtiari, Qashqai and Luri. The weavers usually use wool from their own flocks, giving a sturdy, often dense pile on a cotton or wool foundation, colored with natural dyes in bold, rich tones. Their designs, from geometric medallions to the Bakhtiari garden-panel layout, are woven from memory and passed down through generations. Bakhtiari weaving spread across more than 200 villages after the once-nomadic tribe settled, while Qashqai nomads work on small portable looms, so their rugs seldom come in large sizes.
