Rugs from the city of Hamadan in western Iran, a long-established weaving region, and from the more than 1,500 villages around it, which together produce thousands of designs. Village pieces, often woven by families at home in winter, are usually smaller rugs or runners (some longer than 20 ft, about 6 m) in geometric, hexagonal- or diamond-medallionA large motif at the center of a rug's field, around which the rest of the design is organized; the large central medallion is said to have been introduced in the Safavid era (16th-17th centuries). Floral medallions, typical of city rugs such as Tabriz, Kashan and Sarouk, are often read as a lotus blossom, and the motif has also been read as mirroring the interior dome of a mosque; geometric ones, often hexagonal or diamond-shaped, mark village and tribal rugs such as Heriz and Zanjan. A medallion may stand alone, come with four corner pieces, be flanked by smaller medallions above and below, or repeat down a runner. Rugs with no central motif are called allover. In a well-made rug the medallion sits at the center and the corners mirror one another, as closely as handwork allows., or Herati designs in red, deep blue, and cream, tied with the symmetrical Turkish knotOne of the two main knots of hand-knotted rugs, also called the symmetrical knot (the other being the asymmetrical Persian or Senneh knot). The yarn is looped around two adjacent warp threads with both ends emerging between them, so the back shows small, even, squarish knot heads; weavers often tie it with a hook. Named after the town of Ghiordes (modern Gördes) in Turkey, it is typical of Turkey, the Caucasus and northwestern Iran (Tabriz, Bijar, Heriz, village Hamadan), where Seljuk Turks are said to have introduced it, and gives a durable, precise pile. The Persian knot is often credited with finer detail, yet knot type is a tendency, not a limit: Tabriz rugs woven with the Turkish knot reach about 500 knots per square inch (roughly 78 per cm²). at a densityA measure of how tightly a carpet is packed. In machine-made carpet it describes the fibers in the pile and is calculated by multiplying the face weight by 36 and dividing by the pile height; higher density generally indicates better durability and performance. In hand-knotted rugs it means knot density (KPSI, knots per square inch), counted on the back and averaged over several areas (150 KPSI is about 23 knots per cm²). Like image resolution, higher density allows finer curves and sharper designs, usually with a lower-trimmed pile and more labor, but it is not the sole measure of quality: bold geometric village rugs are made at low to medium density. that is usually low to medium. City workshop pieces are more floral and more finely knotted. The pileThe surface of a rug or carpet, made of upright fibers in cut tufts or loops. In a hand-knotted rug it is formed by the cut ends of thousands of wool or silk knots tied onto the warp row by row, trimmed lightly during weaving and given its final height by shearing at finishing. Pile thickness, measured from the back of the rug to the top of the pile, typically runs from low, about 1/8 to 1/4 inch (3 to 6 mm), to high, about 1/2 to 5/8 inch (13 to 16 mm). Fine, dense designs are cut short to keep the pattern sharp; higher pile suits traffic and heavy furniture, lower pile suits door clearance and humid rooms. is woolA natural animal fiber used for the pile, and in some rugs also the foundation, of high-quality rugs. It is durable, resilient, stain resistant and flame resistant, feels soft and cushioned underfoot, insulates against cold, and takes up dye readily and holds it for many years. It also traps dust particles, which helps reduce allergic reactions. Quality depends above all on where the sheep graze: high-elevation pastures and good feed give thicker, oilier wool, with Manchester, New Zealand and Ghazni wools the best-known prized examples. Early-spring shearing and hand spinning (finer, softer thread than machine spinning) improve it further, while thin, dry wool from dead sheep goes into cheaper rugs. on a cotton foundation (wool in some older rugs), and the single-weft construction standard around Hamadan tends to give a soft pile thinner than in double-weftedA construction in which two weft threads, rather than one, are run through the warp between successive rows of knots. The doubled weft covers the foundation, so on the back of a finely and tightly woven rug only knots and weft show, without the white flecks of warp that give away a single-weft rug, and the rug is thicker, denser and heavier. Bijar and Heriz are typical double-wefted types, as are finely woven Persian rugs in general. rugs.
Tribal rugs woven by nomadic weavers in the Zanjan region in the west of Iran, near the BijarRugs from the city of Bijar in Kurdistan province, northwestern Iran, and the villages around it; the name covers both fine and coarse double-wefted pieces, woven by Kurdish tribes and, in workshops, Afshar weavers. Nicknamed the “iron rugs” of Iran, they are among the heaviest rugs for their size: double wefts, symmetrical (Turkish) knots, and rows beaten down hard, often while the wool is kept wet, give a thick, dense pile. Designs run from floral, Herati, and medallion to geometric, drawing on Isfahan and Kashan as well as Russian, Caucasian, and European sources (a French-style rose bouquet among them), in jewel tones of rust, red, beige, and navy. Bijars are often small rugs or runners, large sizes are rare, and the flat-woven ends and fringes are typically braided. and Hamadan weaving areas. Compact, portable looms, set up on the winter plains, keep most pieces to about 4 x 6 ft (1.2 x 1.8 m) or smaller. The foundation is usually cotton and the pileThe surface of a rug or carpet, made of upright fibers in cut tufts or loops. In a hand-knotted rug it is formed by the cut ends of thousands of wool or silk knots tied onto the warp row by row, trimmed lightly during weaving and given its final height by shearing at finishing.

Bijar-influenced pieces have a heavy-duty pile almost as thick as a true Bijar's, which is why they serve as a Bijar alternative; Hamadan-influenced pieces follow Hamadan designs and colors with a slightly thinner pile than Hamadan rugs.
