Weaving - Wikipedia

Weaving is a method of textile production in which two distinct sets of yarns or threads are interlaced at right angles to form a fabric or cloth.Other methods are knitting, crocheting, felting, and braiding or plaiting.The longitudinal threads are called the warp and the lateral threads are the weft, woof, or filling.
