If the yarn comes in a hank (that twisted circle of yarn) you can unwind it and wind a center pull ball
. If the yarn comes in a ball or a skein, you don't need to rewind it but it helps to find the inner end of yarn and pull yarn from the center. That way the ball doesn't roll around as much.
You can also put the ball of yarn into a container or a plastic bag with just a small opening and that'll keep it from tangling and shedding.
Glad the tam worked out so well. Happy Easter!
