The interlacing of long, thin materials, such as yarn or thread to make cloth (fabric) or baskets. The use of wool, cotton, silk, flax, or some other plant or animal fiber yarn or thread to produce textiles of various sorts by criss-crossing the yarns together in at least two directions. Warp threads are those which run up and down the length of a piece of textile, weft threads are those that run across the weave at right angles to the warp. Many different patterns are possible, producing different kinds of textile and styles of weave. Patterns can be introduced by using different colored threads in a set order. The earliest evidence of weaving is that represented as textile and flexible basketry impressions on burnt clay from Pavlov in the Czech Republic which date to between 25000 and 23000 BC. The oldest woven cloth so far discovered is made from flax, dates to about 7000 BC, and comes from Çayönü, Turkey.
