Bidjar is the name of a small Kurdish town in western Iran. Often referred to as "The Iron Rug of Persia", these Kurdish rugs are distinguished by their highly packed pile, which is produced by a special technique known as "wet weaving", with the help of a special tool. The colours of Bijar rugs are exquisite, with light and dark blues, and saturated to light, pale madder red. The rugs are made with Turkish knots and are generally red and blue with beige elements. The most common pattern is the Herati, but also medallions and floral motifs are used.
