Weaving is a process of making fabric with two separate sets of yarns called the Warp and the Weft. The Warp yarns in the form of sheet (called warp sheet) are wrapped on the beam and runs the length of the fabric. The Weft yarn is entirely separate yarn than the Warp yarns and it is laid between two layers / sheets of the Warp yarns (called Shed) across the width of the fabric. A new shed is then formed in accordance with the desired weave structure, with some or all of the ends in each sheet moving over to the position previously occupied by the other sheet. In this way the Weft is gripped between two layers of the Warps. Here one Warp yarn is called an End and one Weft yarn is called a Pick.
