A modern early 20th century Art Deco area rug rectangle, the ivory field with an overall reciprocal pattern of wavy blue lines within an inner triangle and zigzag border and an outer midnight blue solid border. Many weaving centers have produced carpet rectangles specifically for narrow spaces, adapting their age-old designs to suit this format. Perhaps the most renowned weavers of vintage carpet rectangle were the Bidjar tribe of Northern Iran whose sturdy weavings withstand the wear and tear of stair treads and busy passageways. Superb antique rectangle shaves have been produced in the city workshops of Tabriz and Kirman, as well as in rural communities of Northwest Persia, and villages of both the Caucasus and rural Anatolia. Antique carpet rectangles are often utilized as a compliment or a contrast to adjacent European Art Deco rugs, or as the transition linking two separate rooms.
