Deep-Cut Studios have manufactured some gridded mats in different sizes for me – these are useful for To the Strongest! and other games that require a gridded surface, such as Rommel.
Above is the Russian steppe mat – I now have this with 10cm and 15cm grids (or without a grid), in 4' x 3', 6' x 4' and 8' x 4'. The Russian Steppe mats can be found here.
I've also added new 10cm (4") and 15cm (6") grid sizes for the plains mat (above).
…and new 10cm (4") and 15cm (6") grid sizes for the Sagebrush steppe mats (above).
Deep-Cut mats are printed on a thin, 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. I regularly export overseas. These mats (along with many other designs) can be found in the BigRedBatShop.
Please note: If you want any of the mats in a different size or printed with a different grid overlay (hexes, for example), drop me a line via the shop, and I can arrange it.
