Weaving is a method of textile production in which two distinct sets of yarns or threads are interlaced at right angles to form a fabric or cloth. These sets are called the warp and the weft. The warp threads run lengthwise and are held taut on a frame or loom, while the weft threads are drawn through and inserted over and under the warp.

• Warp: The set of lengthwise yarns that are held stationary in tension on a frame or loom.
• Weft (or Filling): The set of yarns that are drawn through and inserted over and under the warp yarns.

The process can be done by hand, using simple tools, or by machine, using complex automated looms. Weaving is one of the oldest surviving crafts, with evidence dating back to the Paleolithic era.
