A geometric drawing built around six-sided shapes, best known as the hallmark of Abadeh rugs, where a large hexagon spreads over the field, often with smaller ones toward a central rosette medallion. Abadeh weavers developed it to make their rugs stand out from other rugs of the region. Hexagonal or diamond-shaped medallions are also typical of Hamadan and Malayer rugs, and older Zanjan rugs set a hexagonal medallion around the center medallion as a frame.
Tribal rugs woven by nomadic weavers in the Zanjan region in the west of Iran, near the Bijar 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 pile is wool from the weavers' own sheep, in geometric or Herati designs with beige, deep red and blue as main colors; older pieces often show a central medallion framed by a hexagonal one. 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.
