Tapestry is a form of textile art, traditionally woven by hand on a loom. Tapestry is weft-faced weaving, in which all the warp threads are hidden in the completed work, unlike cloth weaving where both the warp and the weft threads may be visible. The weft-faced fabric design is made by using coloured filling yarns, only in areas where needed, that are worked back and forth over spun warp yarns, which are visible on the back.  Most weavers use a natural warp thread, such as wool, linen or cotton. End-uses include wall hangings and upholstery.
