the weavers use a primitive type of throw-shuttle pit looms for the production of exclusively cotton fabrics with pure zeri. they do not use any type of improved appliances such as dobby, jacquard, jala, etc. for the production of designs for cloth with extra warp and extra weft. identical appearance of designs, including warp and weft stripes on the face and backside of the fabric is obtained by this technique of weaving.
