In the mountains Zagros, west of the city of Isfahan, around the town of Shahr-e-Kurd, live the nomads Bakhtiar. Their rugs are known for the design with various repeating squares in which flowers and animals are depicted. For this reason the design is called "garden"(Khesti). Their rugs are very durable with a dense weave and very good quality Persian wool coming from sheep grazing at a high altitude. The best Bakhtiari rugs with highest knot density are often called Bibibaff.
