Hand-knotted carpets are produced by one of the most customary and fascinating techniques of weaving Indian carpets. In this technique, once a particular design for the rug is decided, the rug is placed on the loom. Wraps are then made vertically on the loom. The weavers make knots on the warps and then cuts it before moving on to subsequent knot. The weaver then arranges horizontal rows of wefts across the warps. This creates a pile effect. After weaving all the knots the weaver inserts the wefts which give suitable thickness to the rug. These wefts are made of silk or wool or cotton. The weaver starts creating knots. He takes warps in the same row and ties a knot around them. More the knots more sophisticated the design.
