I've just added several larger gridded Deep-Cut Mats to the shop. These 8' x 4' approximate (2400mm x 1200mm) cloths are printed with a light 15cm grid, and are a convenient size for larger games. These can also be purchased without the grid, as shown below.
I've also received a big restock today, and most of the mats that I'd recently sold out of are now back in stock.
The Deep-Cut Mats I sell are printed on a light cloth, and can be washed, ironed, and folded or rolled away for storage. Hills can be placed on top or even, if shallow, underneath. These mats (together with the plains, fields, steppe, desert, winter and wasteland mats) can all be found in The BigRedBatShop.
