Yarn is usually "put up" or packaged in one of the following ways:
1. In a skein (pronounced "skān"), a long and thin cylinder shape.
2. In a ball.
3. In a hank, which loosely wound into a large ring shape and then twisted on itself. It needs to be wound into a ball before use.
4. On a cone. Cones come in different sizes and hold more yarn than a skein or ball.
