Weaving is a method of textile production that involves interlacing two sets of yarns at right angles to each other on a loom. This crossing of yarns forms a fabric or cloth. Knitting is another method that uses a single yarn and two needles to form loops that interlock in rows, giving the resulting fabric more stretch than woven fabrics. The document then provides various reasons for and remedies to common faults that can occur during weaving and knitting processes.
