Producing of luxury carpets begins with the following: a designer draws a sketch on a sheet of paper in one quarter of a carpet, and then by symmetric imposing completes the whole picture. This sketch is painted, put on graph paper and goes to an artisan who in accordance with it weaves luxury carpets. The basis is pulled n a special wooden frame and pile is woven into it by hand. Each thread is tird with a special knot. A handy woman pends about two seconds for each knot, tying en to fourteen thousands of knots a day. Only after one month of such work the picture of the future carpet begins to show. When luxury carpets are produced the speed of weaving depends on the complexity of ornament, the work finness and material from which luxury carpets are made. But the quality depends on the number of knots per square meter: the more, the sharper the image, the denser, stronger and more expensive the carpet. However, too high density may in some cases cause death of luxury carpets – a carpet can crack at the joints, for example, if rolled clumsily. Original Persian luxury carpets are very dense (one to two and a half million knots per square meter). Knots must be smooth and their location must be ordered. Only thin girlish fingers can tie a tight knot, that’s why teenage girls are often involved in carpet weaving. On average, it takes from several months to three years to create a handmade carpet. If you look at the underside of luxury carpets, picture and colors will be clean. Sucha carpet differes advantageously from a machine made carpet which has a blurred picture. After every weaven 7-10 centimeters the carpet is neatly trimmed and left a pile length of 2-2,5 cm. Only then the ornament is shown from irregular weave of colored threads. Ready luxury carpets are cleaned with sandpaper by an artisan.
