Drape the hank on the lampshade of a LARGE lamp. Make sure it can spin freely. Grab one of the hank ends (usually the one on the outside will be easier to find)...when you snip the knot you can tell by the tension that it's connected... and start winding. (If you place the lamp on the floor you can stand above it.) Otherwise, as noted, you can use back or legs of chair, another person's hands, your feet or knees, etc.
