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.
Village rugs from the town of Malayer and neighboring villages between Arak and Hamadan, usually dated to about the 19th century and woven on an old trade route that brought in outside designs. A cotton foundation, wool pile and symmetrical Turkish knot give a finer weave than most village rugs, with the pile clipped fairly low to show detail. Diamond or hexagonal medallions, small white dots in the border ringing the medallion and a rope-like loop effect in the rug's own border are typical marks. The south-eastern, Sarouk-like style is double-wefted and thicker, with floral medallions or Tree of Life designs; the north-western, Hamadan-like style is single-wefted, geometric and lighter in color. Small rugs and runners predominate, mostly on navy, deep red or cream grounds.
A construction in which the weaver passes just one weft thread between successive rows of knots. Because the warp is not fully covered, the back of the rug shows a zigzag of small white foundation specks, an easy way to recognize it, and the pile tends to be thinner and lower than in double-weft weaving. Single weft is standard practice in the greater Hamadan area, from Hamadan, Karaja and Mehraban rugs to Senneh and many Kurdish tribal pieces, and in the Hamadan-influenced type of Malayer rug.
A design in which one large, elaborate tree rises through most of the field, surrounded by botanical ornament, with birds, animals and flowers spread among its branches. The tree can also occupy a single panel of a garden-panel rug or appear as a border pattern. In Persian tradition it stands for the connection between earth and the environment, is also read as a link between heaven and earth, and symbolizes strength, wisdom and the continuity of life. It is woven in Tabriz, Kashan, Isfahan, Kerman and Malayer rugs and in Baluchi rugs.
