A loom is a device used to weave cloth and tapestry. The basic purpose of any loom is to hold the warp threads under tension to facilitate the interweaving of the weft threads. The precise shape of the loom and its mechanics may vary, but the basic function is the same.

Tapestry is a form of textile art, traditionally woven by hand on a loom. Normally it is used to create images rather than patterns. Tapestry is relatively fragile, and difficult to make, so most historical pieces are intended to hang vertically on a wall, or sometimes horizontally over a piece of furniture such as a table or bed. Some periods made smaller pieces, often long and narrow and used as borders for other textiles. Most weavers use a natural warp thread, such as wool, linen, or cotton. The weft threads are usually wool or cotton but may include silk, gold, silver, or other alternatives.
