When people ask how they should prepare for their move, we tell them to "box it, bag it, break it down." It helps things go fast and keep costs low.
I came across this picture today. While I have to deduct points for not using uniform-sized boxes, it's still THE best use of space and symmetry I've ever seen.
Prepare like this and we'll knock your move out in half the time. (Just leave one square foot empty so we can start removing items...)
