Warp
The set of threads stretched lengthwise on a loom, through which the weft is passed.
Also: tana, pavu, taana
The warp is the set of long threads held under tension on the loom, running along the length of the cloth. The weaver raises some of them and lowers the others to make a space, called the shed, and passes the weft through it. The number of warp threads decides the width and the fineness of the cloth. The warp must be strong, because it carries the tension of weaving, so it is often sized, a light stiffening, before it is set up. In a saree the warp runs from the pallu to the other end. The Hindi word is tana.
