Weavers' frames, also known as LOOMS, are tools used by weavers to create fabric. They consist of a frame with a series of threads stretched across it, which the weaver can manipulate to create patterns in the fabric. The threads are held in place by a series of pegs or nails, and the weaver uses a shuttle to pass the thread through the frame. The loom allows the weaver to create complex patterns and textures in the fabric, making it an essential tool for weaving.
