Nain Rugs : Nain rugs: Nain is a small city in central Iran, near the famous city of Isfahan. Before the start of the 20th century, it was known for producing high quality handmade woolen fabrics. However, due to the decline of the town's business activity, they commissioned weavers from Esfahan to weave handmade rugs. They created their own style using bright, creamy colours and shades of blue or red with a large medallion in the centre. The high knot density and high class materials (wool and silk) establish Nain as very high quality rugs. They are often woven in areas around the city Nain, not necessarily in the city itself. The familiar pattern of Shah Abbas have been successfully used in the Nain rugs. The warp in these rugs is typically of cotton. The warp consists of a number of threads that are referred to as "La". Fine woven Nain have 4 threads (4La) or 6 strings (6La). Today, the city Nain produces only very stylish 4s or 6s of quality La. 9 and 12 La are produced mostly in Khorasan, i.e. Kashmar and Mashhad. A Famous house in town Nain is the house of Habibian. The rugs woven in their workshops are the best and most sought after rugs in the world.
