Persian Kelim Old are often oblong, and were originally used in tents by the nomads. Kelim rugs are often placed on top of other rugs as insulation. The rugs are often up to 50 years old, sometimes more than 80 years. The nomads knot or weave the rugs they need themselves, and use them for many different purposes, such as saddlebags for camels and donkeys, but they are mostly used for motorbikes, storing clothes, for sitting on, and as sleeping blankets.
