I remembered one more of my "rules for packing":
5. Pack it Tightly
I don't mean make the boxes heavy, or crush things. I do mean use every single bit of space. The less room things have to shift, the less likely something's going to get broken or damaged. No space at the top of the box means when they're stacked they won't cave in and crush the contents. So when you pack your books and there's little nooks and crannies left, stuff socks and underwear in there. Put a towel or clothes on top of everything before you tape it shut. Slip paperbacks into small spaces in other boxes; top off large boxes with lightweight stuff like pillows and stuffed animals; add kitchen linens around the inside of boxes of plates and cups. Any time you can cram something into a box, do it. You'll cut down on the amount of boxes you have to move, and your stuff will be much more secure. It will also add some amusement to your unpacking process, like when you really need a cup of coffee the first morning in your new place and you have to pull four pairs of lacy Victoria's Secret underwear out of a box to get to your favorite mug.
*Boxes: A friend tipped me off to a good source for moving boxes - egg boxes. She said:
"Go to the grocery stores and ask what day the eggs come in and if you can get boxes. Go every time they get a shipment and grab as many as you can. Free and very sturdy. They even have handles and they are a good size. Note: this tip does not apply to produce boxes."
