Kashan Kashan rugs are woven in workshops of the city of Kashan, in north central Iran. Kashan style, like most Persian styles, is copied by other areas of Iran as well as other countries such as India, China and Pakistan. Their pattern is almost always curvilinear. One traditional design is an elongated diamond-shaped and lobed medallion with floral (usually Shah Abbasi) pendants. This design is one type of the Shah Abbasi medallion. The entire rug including the medallion itself, the corners (in the case of medallion-and-corner), the borders, and the field are filled with Shah Abbasi and islimi motifs. It is common for this traditional design to have a navy medallion with similar corners and border in a red background or vise versa. Quality Kashan rugs and carpets are of excellent quality. Older ones (before 1945) are very good, but some of the newer ones are not as good. They sometimes have lower KPSI and they are chemically dyed. On the other hand, if you are a wise buyer, you can find a great deal. Kashan rugs and carpets are one of the finest looking carpets in Iran and the world.

Foundation The foundation (warp and weft) of the rug is cotton, except in very fine pieces where it is pure silk.
