Heriz for a long time was well known in Persia and abroad for the long-lasting woolen and silk rugs woven in pleasant and agreeable colors. Although the method of weaving these rugs is the same, yet they rarely resemble each other, they are produced in Heriz and thirty nearby villages in medium and big sizes as well as runners. The design of Heriz rugs is normally stylized with a very big medallion in the center that almost covers the field; the corners, too, resemble the center medallion. The predominant colors are ivory, brownish red, dark and bright pink, and blue.

Recently the designs of Heriz rugs are copied by Indian and Rumanian weavers, but they are easily distinguished from the original ones as the texture and the colors differ a lot from those woven in Heriz.

The designs of old Heriz rugs differ radically from those of new pieces.
