The Making of a Rug
sheared from the sheep twice a year, in the spring and in the autumn. Generally the wool from the spring shearing is considered superior and is used for making most rugs, bags, and clothing. Wool from the autumn shearing or from dead animals is less fine and is used mainly for making felts or tent fabrics. In some areas, tribal weavers also use cotton. Although cotton is actually more stable than wool, it is less durable and often more expensive than wool, so its use is limited. Finally, a much smaller number of rugs are made using silk, which is typically purchased from traders who bring it from manufacturing centers far away from the tribal areas.The oldest known hand-knotted oriental rug was excavated from the Altai Mountains of Central Asia near Pazryk in 1949. It was found in  a semi-frozen Scythin burial mound. This rug dates from the 5th century B.C. and is called "The Pazryk Carpet". Today the rug is in the Hermitage Museum in St. Petersburg, Russia. The carpet is sophisticated with floral, geometric, and pictorial designs. This legendary piece is excellent testimony to the durability of the weaver's art. Few other rugs are known to have survived more than 500 years. Many of those are displayed in museums around the world. However, it isn't uncommon to find rugs over 100 years old that are still in usable condition, and some that, even today, are being walked on by great-great grandchildren of the original owners.hroughout the Middle East and Central Asia, The art of weaving rugs has been  practiced and revered since ancient times. Many cultural historians think these rugs, in addition to having beauty and practicality, also reflected very practical concerns of day to day life. One thought is that hand knotting carpets with a pile began among nomadic peoples as a means of imitating the texture and warmth of animal pelts. Whatever factors may have contributed to its initial development, the art of rug making quickly took on a central role in the aesthetic and historic identity of entire regions. the fibers several times. Once clean, the raw fibers are spun into threads using a weighted object called a spindle. When a twist of the raw wool or cotton is attached to the spindle and the spindle is spun and dropped, it pulls the fibers out of the bunch and winds them into a long thread. After several threads have been made, they are in turn spun together to form a yarn. Typically two or three threads will be used to form a yarn. Yarn is normally spun in the opposite direction from the threads so that the fibers will bind together more tightly. and iron sulfate. Once the yarn has been treated it is ready to be dyed. Traditionally the dyes used are made from natural local plants. For example, the madder plant yields a red dye, milkweed and buckthorn produce yellow, dyer’s woad and indigo produce blue, while browns and blacks can be made using walnut shells or iron filings. Since the late nineteenth century, some tribal weavers have also been using factory-produced chemical dyes. Most yarn is dyed in batches. Sometimes when the dye runs out in the middle of the dyeing process, the batch is finished with another dye lot. This produces yarns with slightly different colors that, when woven together, produce a chromatic shading effect called abrash, which is greatly admired by many Western collectors.

determine the basic size and shape of the rug. Alternate warps are then attached to horizontal bars called heddles. When the heddles are raised and lowered, they create a space between the warps that is called the shed. Another yarn, called a weft, is attached to a weighted object, called a shuttle, and passed back and forth through the shed. Alternating which warps are raised and which are lowered produces a fabric of interlocked yarns that is called a plainweave. Sometimes each weft will be beaten down on top of the previous one to create a fabric in which only the wefts are visible. This type of fabric is called a tapestry weave (or kilim weave.) Other times the wefts will be wrapped around the warps according to a set pattern to create a more textured fabric that is known as a sumak weave (or brocade weave.) Finally, the weaver can tie extra bits of yarn to the warps between one or more rows of wefts. The extra bits of yarn, which can be tied in either symmetric or asymmetric knots opening either to the left or to the right, stick up above the warp and weft foundation to create a pile weave. In some cases, several different weaving techniques may be employed together to produce a rug that has a variety of textures and visual effects.
