These printed cloth gaming mats have been manufactured by Geek Villain for gaming with To the Strongest! They are a minumum of 6' by 4' (1800mm x 1200mm) in size, but are deliberately cut somewhat oversized, usually around 76" by 56", in order that they hang over the edges of a typical 6' x 4' gaming table.

Geek Villain mats are made from a high-quality durable fleece. The material used has a grassy “texture” on both sides, and has a degree of stretch to it, which allows hills to be placed beneath it. The grass design is perfect for many parts of Europe, Asia and North America. 

n.b. the second image shows a cross-gird- there is no cross grid on this mat.
