Replacing Nintendo DS Lite Screen

I'm in the process of replacing the top screen on my daughter's Nintendo DS Lite. There are many little screws and several sizes of each. To keep them straight for easy reassembly, I had a brainstorm.

I took a sheet of laminating paper, flipped it sticky side up, then taped a piece of white paper under it. Then, drew a (very) rough picture of where each screw goes. Now, if I sneeze again, I won't lose track of where they all belong. I wish I thought of that when I took the first one apart - the donor DS I got the screen from.
