A curvilinear or floral design is most closely associated with a Persian rug, although geometric designs are used as well. The major production centers can be found in Northwest Persia, Western Persia, Southwestern Persia, Central Persia, Southern Persia, and Eastern Persia. Named after the village, town or district where the piece was woven or by the weaving tribe, each Persian carpet has attributes specific to a geographic region or tribe.
