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 or filling. Weft is an old English word meaning "that which is woven"; compare leave and left. A fabric band which meets this definition of cloth warp threads with a weft thread winding between can also be made using other methods, including tablet weaving , back strap loom , or other techniques without looms. The way the warp and filling threads interlace with each other is called the weave.SEE VIDEO BY TOPIC: How Its Made - 287 Fibreglass Insulation
