i work in a bookstore where we used to sell posters. the display case was thrown out after we stopped, so i grabbed all the inserts. they're a layer of white cardboard, about 3'x4', with a sheet of plastic on each side. i took one, drew a grid on the cardboard with a sharpie, and experimented to test that the plastic would stand up to dry-erase markers. one stunning success later and now i have friends wanting them for 1.25 inch plastic-crack figures, grids, and everything else. the metal frames the boards came in sit in the garage and protects them when they aren't on the table.
