Which fiber art technique involves condensing or matting fibers together?

The technique that involves condensing or matting fibers together is felting. This process can be achieved through methods such as wet felting or needle felting, which both rely on the physical entanglement of fibers. During felting, wool fibers are agitated and compressed, causing the scales on the wool fibers to interlock. As a result, this creates a permanent, dense fabric known as felt.

In contrast, spinning focuses on transforming fibers into yarn, weaving involves interlacing threads or yarns at right angles to create fabric, and knotting is a method of tying fibers together but does not involve the matting or melding of fibers in the same way as felting. Therefore, the essence of the question highlights the unique property of felting that distinguishes it from other fiber arts.
