Start out with the female end between your thumb and pointer finger

While holding the female end wrap the cord around your and
and overlap the female plug holding it in place

After you have made several loops around your hand, slide your
hand out and hold it with only your fingers

Now begin to wrap the cord in the opposite direction, helping to form a ball

After wrapping several times in the opposite direction, pull your
hand completely out and just hold the ball

Continue wrapping the cord around the ball, and be sure
to wrap it evenly to keep the ball shape

Once you have made several balls, you can throw them into a rubber tub for storingThe ball shape is also very useful when putting lights up the following year.
