Deep-Cut Studios have manufactured a new gridded mat for me – a larger 6' x 4' (1800mm by 1200mm) Western Desert mat with a 10cm grid. Gridded mats are useful for games such as To the Strongest! and Rommel. I personally use the Western Desert for ancient and modern gaming in the Middle East; this grid size is particularly useful with 15mm and smaller minis.
N.B. I also sell similar but ungridded mats.
The grids are marked with a thin, unobtrusive black line. The various Western Desert mats and grids can be found here.
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.
