Tea and twine?

To keep a ball of string/twine from knotting and easily available: store it in an old teapot that you don’t use. Thread the string through the spout of the teatop and put the “ball” in the main part of the teapot. When you need a piece of string or twine, simply pull a piece of of the teapot spout and cut off at the length you need. The rest of the ball is ready and waiting for you in the teapot.
