After moving many times, I found that it helps to work a room at a time, number the boxes and make a list.
For example, in the kitchen. I would start packing a box and mark it on the outside KITCHEN #1. On a pad I would write KITCHEN #1 and list the items in the box (casserole dishes, silverware, mixing bowls, etc).
I do this for each room in the house. Then, after the move, if I am frantically searching for one thing (which box is the small frying pan in???), I can look at my list - see that it is in KITCHEN BOX #3 and go straight to that box.
Hope this helps. It has worked for me.
