The outline of a rug loom looks like a wooden frame. Warp threads are vertically wound around the loom parallel to each other, depending on the type and size of the rug. After preparing the warp, a chain like plait is woven, leaving a margin of fringes and then a few cm wide kilim weaving is done so as to prevent the pile knots from shifting and dropping out. Upon completion of this procedure, the rug is ready for weaving.

The weaver hangs the coloured knotting threads wound into small balls together with the rug design, drawn on a quadratic board, somewhere within reach. The type of the quadratic heet used depends on the type of the rug and the density of its knots. A quarter of the rug in a symetric model with a center pattern and a half of the niche design is drawn on 1/2 quadratic sheet. Each knot on the rug corresponds to one square on the quadratic sheet and its colour is designated by the paint covering the respective square. Sitting on a small tool, the weaver begin weaving the carpet from the bottom upwards. As the weaving progresses, the rug is shifted behind the loom. Upon completion of a row of knots, the weaver passes the horizontal thread called weft through the warp threads (below and above) across the width of the rug and firmly presses on the knots with the shed stick.The ends of knots which have been cut roughly with a knife at the time of each knotting are then trimmed with a special pair of scissors to make them even with the face(pile) of the rug. The two methods used in rug weaving are Turkish knot and Persian knot. Although the single knot method largely facilitates working with detailed motifs, the double knot method produces an extraordinary strength. Carpets woven with the double knot method, therefore turn out to be an important means of investment as they stand better against wear and tear in time. Upon completion of the rug, another kilim weaving is done so as to fix the knots. Finally, chain plait is woven and the rug is cut to loose from its warp to be taken out of the loom. It is then washed with soapy water to get rid of the dust and dirt collected during the course of weaving and made ready for use
