In weaving, two distinct sets of yarns or threads, called the warp and the filling or weft (older woof), are interlaced with each other on a loom to form a fabric or cloth. The warp threads run lengthways of the piece of cloth, and the weft runs across from side to side. Woven cloth can be plain (in one color or a simple pattern), or it can be woven in decorative or artistic designs, including tapestries.
