Okay so if you have played Scythe you know the player boards how they are like 2 on top each other with the indents for the figures to sit in. A game idea I am working on would benefit greatly from that type of board but on a much larger scale. It would be a 10x10 board and the openings would be just slightly larger than Bridge Card Sized. The point would be to lay cards into these cuts so they sink down a bit, but I am not sure the best way to create that. I was thinking Foam Core glued to cardboard but then I wondered how that would hold up. Any thoughts on how to make a homemade dual compression board?
