Yarn is a long, continuous length of fibers that have been spun or felted together. Yarn is used to make cloth or different wearable accessories including shoes, hats, scarfs, etc. by knitting, crocheting or weaving. Yarn is sold in a shape called a skein to prevent the yarn from becoming tangled or knotted.

Yarn can be made from any number of natural or synthetic fibers such as wool, cotton, silk, or acrylic. Some yarns are made from a blend of several kinds of fibers.
