Tapestry is a heavy, handwoven cloth with designs made by separate weft threads that interweave only with the warp when required for the pattern. The binding is usually tabby and weft-faced, and the weft threads are usually of different colours. As most tapestries are woven on looms without a beater, the wefts do not have to lie strictly at right angles to the warp threads. Instead they may follow the contours of the design much more freely.
