Weaving is the premium method of elastic construction. It results in a finished webbing which does not narrow when stretched, and does not "run" when snagged. With woven webbing it is possible to create a much denser material, and/or a more complex interlocking of threads. Woven web can vary from lightweight insert type to mammoth heavy duty webbing. For hand, absorbency, and overall quality, cotton is the preferred fiber. Polyester is harsher and shinier, but less costly.
