Making something on a loom is an ancient craft that has been practiced for centuries. Weaving is the process of interlacing two sets of threads or yarns together at right angles to form a fabric or cloth. The threads that run lengthwise are called the warp, and the threads that run across are called the weft. The weaver uses a shuttle to pass the weft thread back and forth through the warp threads. This process creates a variety of patterns and textures, depending on the type of loom used. The end result is a beautiful piece of fabric or cloth.
