What are Warp and Weft ?
In tapestry weaving the warp threads are those which are vertical during weaving. The weft threads are those woven between the warps. It is the weft threads which define the pattern and provide the colours. Unlike cloth fabrics, the weft threads do not run continuously across the tapestry, but form patches of colour.
The terms warp and weft are used in reference to textiles, specifically those which are woven. In the literal sense, warp and weft are the technical terms for the two types of thread used to create a finished woven product. The warp is the tightly stretched lengthwise core of a fabric, while the weft is woven between the warp threads to create various patterns. Some people also call the weft the “filler” thread, since it fills in the design, and the archaic “woof” is also used instead of weft in some regions.
