Have fun with your new yarn.
The hank has a bit of a twist in it, almost knot-like. Carefully untwist it so that it becomes a big wheel of yarn. There will be several places around the circle where it is tied to keep it neat. Cut or untie those. Find the end of the yarn and have someone hold the circle (like in the olden days) or put it on a chair back. Roll it off the loop into your ball. I have put mine over a swivel computer chair. Then as I roll it into a ball I keep spinning the chair around. Works pretty well.
