before a new colour is implemented. The most popular of flat-weaves is called the Kilim. Kilim rugs (along with jewellery, clothing and animals) are important for the identity and wealth of nomadic tribes-people. In their traditional setting Kilims are used as floor and wall coverings, horse-saddles, storage bags, bedding and cushion covers. Various forms of flat-weaves exist including: Herati Jajim Gelim (Kilim) Maleki Sirjan Soumak (Soumakh) Suzani Design Formats and special types Ghali (Persian: , lit. "carpet"): large format carpets (190 × 280 cm). Dozar or Sedjadeh: The term comes from Persian do, "two" and zar, a Persian measure corresponding to about . Carpets of Dozar size are approximately x . Ghalitcheh (Persian: ): Carpet of Dozar format, but woven in very fine quality. Kelleghi or Kelley : A long format, ca. x . This format is traditionally placed at the head of a ghali carpet (kalleh means "head" in Persian). Kenareh : Smaller long format: × . Traditionally laid out along the longer sides of a larger carpet (kenār means "side" in Persian language). Zaronim : corresponds to 1 ½ zar. These smaller rugs are about long. Nomadic carpets are also known as Gelim (; including Zilou, meaning "rough carpet". In this use, Gelim includes both pile rugs and flat weaves (such as kilim and soumak). Field design, medallions and borders Rug design can be described by the way the ornaments are arranged within the pile. One basic design may dominate the entire field, or the surface may be covered by a pattern of repeating figures. In areas with traditional, time-honoured local designs, such as the Persian nomad tribes, the weaver is able to work from memory, as the specific patterns are part of the family or tribal tradition. This is usually sufficient for less elaborate, mostly rectilinear designs. For more elaborate, especially curvilinear designs, the patterns are carefully drawn to scale in the proper colours on graph paper. The resulting design plan is termed a "cartoon". The weaver weaves a knot for each square on the scale paper, which allows for an accurate rendition of even the most complex designs. Designs have changed little through centuries of weaving. Today computers are used in the production of scale drawings for the weavers. The surface of the rug is arranged and organized in typical ways, which in all their variety are nevertheless recognizable as Persian: One single, basic design may
