Looking for a transparent plastic sheet. It's gotta be semi pliable and not rigid. maybe 1mm thick. Need a normal paper size, if it's a big sheet, I can always cut it down. What comes to mind is the transparency used for overhead projectors, but that's too flimsy. I'm going to go to Staples and see if maybe their desk pads will work, but if you guys/girls have other suggestions, I'd like to hear it.
