The Yarn Ball Winder by Yarn Valet is a lightweight tool used to wind yarn into uniform, consistent yarn balls. You can create either center pull or outside pull yarn balls. There is no need for expensive, bulky yarn ball winders, this one will fit in your yarn bag! Look for the secret compartment that can hold anything. Ours has stitch markers, crochet hooks and yarn needles that always used to get lost in the bottom of our bags. Visit the Yarn Valet website or You Tube for videos on how to use the Yarn Ball Winder. Use it to wind new yarn into balls or fix a skein that has fallen apart when you get toward the end. It is lightweight and perfect to always have on hand in your yarn bag.
