By the late nineteenth century, weaving in the region of West Persia had reached its Zenith. The establishment of the Manchester firm of Ziegler was indicative of the demand for rugs from this region. The largest market was and still is Europe and the United States. A vast number of rugs were specially commissioned from the looms in the region at this time destined for the great houses in Europe and America. The attraction of these rugs is the superb blend of harmonious colors coupled with a well-balanced design. The rugs have cotton foundation and are woven in 100% wool. The dyes are all from natural plant extracts. The continued popularity of the Sultan Abad carpets means that fine examples are becoming increasingly rare to find on the market today.
