The central Iranian city of Nain is renowned for its exquisite culture of rug making, which began relatively recently in the 1930s. Nain rugs are famous for their extraordinary level of detail and the fine quality of the materials. The exceedingly high number of knots per square inch in Nain rugs allows a level of intricacy that is not possible in other rugs. The designers are free to craft captivating floral patterns around central medallions that have an almost kaleidoscopic quality. The colouring tends to be predominantly light, from ivory to peach with darker colours used sparingly to render details.
