A Nostepinne is a handy tool for winding centre-pull balls of yarn without changing the twist of the yarn.
It's portable and very easy to use. This wooden Nostepinne (a Scandinavian word meaning "nest-stick) by Chiaogoo has a lovely smooth but grippy, matt finish, and is the perfect size for winding all weights of yarn from lace to chunky!
Approximately 11″ (28 cm) long. Instructions on the label.
