Near the border of the central desert and along the road from Isfahan to Yazd is the city of Nain, famous for its fabulous and splendid rugs. Many years ago, the Aba (sleeveless cloak), was finely woven with camel's wool in Nain. Almost seventy years ago, the government of that time prohibited the wearing of old-fashioned clothes. The weavers of the Aba were forced to change their profession and they started a new enterprise.

The result was the creation of the beautiful and fine rugs that gained worldwide fame both in Persia and abroad. In the beginning, the designs were those of Bakhtiari and Yazd rugs, and especially those of Isfahan.

After the Second World War, specific and determined patterns were made which were gathered from the whole collection of rug designs in Persia. One of the special features of Nain rugs is the insistence of the dyers to use cool colors. Their preference is white, dark blue, light blue, beige, and sometimes red.

The dimension of the Nain rugs varies from the smallest sizes up to larger sizes. Warp and weft are made of cotton, the pile is made of wool, they normally use the silk around the motifs to make the design outstanding. The designs often used in Nain rugs are overall Shah-Abbasi animals with multiple antlers, multiple armlets, (Bazu bandi), Shah-Abbasi medallion, and corner.

The weave varies between fine and extremely fine, 3.000 - 10.000 Senneh knots per sq. dm. To determine the fineness of Nain rugs the terms 6-ply (shesh-la) and 9-ply (noh-Ia) are often used. It's correct to explain that whenever one of the warps of a rug is named noh-la. If two of the strings get separated, then the term shesh-la is used. Shesh-la is much finer than noh-la.
