Bidjar is the name of a small Kurdish town in western Iran. Kurdish carpets are often very strong and compact, which makes them extremly durable. The name Bidjar denotes the meaning of durability to many carpet specialists. The weavers use their heavy comb, made of metal and wood, to beat the weft and the knots, so that the pile almost stands up. The surface of the pile therefore, becomes very compact, which prevents gravel and other small particles to be pressed into the carpet. The carpets are made with Turkish knots and are generally red and blue with beige elements.
