A No-Tangle Christmas Light Storage Solution

This is the best invention ever.  I saw it somewhere about two years ago and have been doing it for the past two Christmas'.  Start with a cardboard box.  Cut it into pieces that are approximately 8" x 12".  Cut a slit at the top left corner, leaving about and inch on the left side of the cardboard.  Cut a slit at the bottom right corner, leaving an inch on the right side of the cardboard.  Then wrap your lights around the cardboard, sticking the ends of the strands in the slits you've cut. 

Simple, right?  Right!  I expect thank you cards for this one.  ;)
