These Deep-Cut Wild West design mats are just over 6' by 4' (1800mm by 1200mm approximately). They are very arid, and potentially suitable for games set in many parts of the world. Some are un-gridded, others have a 15cm "cross" grid (indicated by subtle crosses at the corner of the squares).
Deep-Cut mats are printed on a thin, light cloth, which 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 worldwide. These mats (along with many other designs) can be found in The BigRedBatShop.
