I just used a wooden board that I had lying around to pair with this set. At the beginning I was hoping to have the board be made of hardware as well, but I didn't have any inspiration about how that would work. I thought about expanded sheet
, but I don't really see how that would work well.
Since the bases of all the pieces are steel, you could make a board that had a magnet under each square and have it be a magnetic set if you wanted to. 64 magnets is a lot, though!
