A loom is a device used to weave threads or yarn into fabric. It holds the threads in place while interlacing them to create various patterns and textures. Looms can be simple, like hand-held looms, or complex, like industrial looms used in factories. There are different types of looms, including hand looms, treadle looms, and Jacquard looms. Each type has its own mechanism and is suited for different weaving techniques. Looms have been used for thousands of years in many cultures, making them an essential tool in the history of textile production.
