AREA RUG CONSTRUCTION
Before the rug can be woven, the weavers must refer to a full-scale graph paper drawing of the rug, called the cartoon. This is basically a chart in which each tiny square represents one knot. The design is drawn and colored so the weavers know when to change yarns. Next the loom must be strung. The warp is tied vertically to the loom, and then the weft is woven through it in a basket weave fashion. This is considered the foundation of the rug; and it is made from cotton, wool, or silk. In between the layers of weft threads, the weavers tie knots onto the warp in a horizontal row, which creates the pile. Most weavers tie an average of 5000 to 6000 knots per day. Generally speaking, the finer the weave (smaller the knot), the more detailed the design may be. Handmade rugs are often judged in part by the knots per square inch. A coarse weave is typically less than 40 knots, medium is between 40-90, fine is between 90-180, and very fine is 180 and up. Most importantly, the weave should
