I've recently added some new Deep-Cut Design mats to the BigRedBatshop. These 4' x 3' approximate (1200mm x 900mm) cloths are printed with a faint 7.5cm grid.
I anticipate that people might like to use them to play To the Strongest! or other grid-based games, with armies based on 60mm elements (whether 28mm or 6mm minis) – if you have a DBA army, then more than likely you have a TtS! army. The new mats are 16 squares by 12. I have the new grid in two designs:
Above is the Sagebrush Steppe showing the grid, and below the Plains mat, without.
The Plains 7.5cm can be bought here.
The Sagebrush 7.5cm can be bought here.
Mats can also be purchased with different grid sizes (10cm/12cm/15cm/20cm) or without the grid at all.
Deep-Cut mats are printed on a light cloth and can be washed, ironed, and folded or rolled away for storage. I regularly post them overseas.
