Do yourself a favour for next Christmas: When putting away your Christmas lights, instead of stuffing them in a box, wrap them around a plastic hanger. No more tangled mess of lights to struggle with when you pull them out at the end of the year!
If you use a hanger with the little hooks on the body, you can use those to anchor the ends of the lights. And thanks to the hanger's top hook you can hang the whole thing up for storage.
