Sumak Bags of Northwest Persia and Transcaucasia by John T. Wertime

Sumak bags were woven by tribes in the Near East to store and carry articles and foodstuffs, and range in size from small salt bags to large bedding bags. Sumak is not a people or region, but a technique - an elaborate form of flat-weaving. Owing to their sophisticated weaving technique, strong colours and highly decorative design, sumak bags from that region are particularly sought after by collectors.
