Bakhtiari carpets are based on a cotton foundation warp with a wool weft usually taken from the herds of the producing tribe. Patterns are usually floral or garden inspired. The Khesti, an established garden motif, is perhaps the most well-known rug design. The carpet is divided into individual squares with animals and plants acting as symbols. Another influential design features a decorated field with lattice designs and floral ornaments. The use of colors varies depending on styles of certain tribes. Generally they include shades of white, reds, browns, greens, and yellows. Blue does not appear to feature.
