I should have mentioned I have an electric drill, rotary tool, B&D mouse/palm sander, and sanding block.

I watched the Lewis video a few days ago, it was very helpful.

While I don't have a router, I've been wondering how well a router would work on the edge of such thin material. They are made for creating consistently shaped edges in wood though, so it seems like they would work well.

A makeshift guide to keep you sanding at the right angle and something concaved the correct the right shape to put the sandpaper on would be helpful.
