I actually have a GW Battle Mat which is a nice piece of kit & use it for small games (it’s 3X5). To work for a big game (ie cover the entire table tennis table I use) I’d need two. Guess what? They’re out of production (replaced by very expensive plastic tiles).
So, do you know of anything that might match the GW product? Or do I have to buy 2 new ones from someplace?
