Learn how to wind a center pull ball using only your hands. In this video, Grace walks you through the steps of winding a ball of yarn so you can work with the end from the middle of the ball. This is a great technique to know how to do if you don't have a ball winder and yarn swift. 

Sometimes the yarn for your knitting or crochet project comes in a hank instead of a ball or skein. It is much easier to work from a center pull ball instead of a hank. Also a center pull ball won't roll away from you as a ball wound from the inside out would.
