A short encyclopedia entry defining weaving as the interlacing of threads or yarns into a continuous web. It describes the simplest mat weaving of untwisted fibres tied to sticks, then plain weave and the basic twill, illustrated by three small diagrams (a warp setup and cross-sections of plain weave and simple twill). It notes the skill needed, warps of one to two thousand threads, and refers readers to Watson's treatise and related entries on Loom, Twill and Yarn.
