the length wise threads of a woven material are called the ‘warp’. a lightweight silk fabric can have over 2,000 warp yarns.the weaver sends the wooden shuftle flying from side to side by pulling on a cord while simoultanously ‘beating up’ the weft yarn. the basic weaving technique uses the same or different colors in the warp and weft. some villages are experimenting with new designs and color combinations, yet still using their traditional techniques and basic patterns.
