Shirvan is one of the principal weaving areas of the Caucasus stretching from the central east coast some 400 km inland and encompassing towns which produce particular design variations common to the Shirvan group. These include Bidjov, Marasali, Khila, Surahani, Baku and Saliani. The Shirvan rugs are noted as being some of the finest rugs from Caucasian. They are usually thin and densely knotted. The warp threads are usually light and undyed brown sheep’s wool spun together. The wefts are light and thin, and selvages are usually white over double or triple threads.
