The term "yarn" refers to a long, continuous strand of intertwined fibers that are typically spun into thread or woven into fabric. Yarns can be made from various materials such as natural fibers like cotton and wool, synthetic fibers like polyester and nylon, or even metal threads. The thickness, strength, and texture of yarn depend on the type of fiber used and how it is spun into thread. In general usage, "yarn" can also refer to a story or account of something, often told in a lengthy or rambling manner.
