New "grass" mats are in the shop September 05 2016
These are a deep dark green grass mat that would suit Northern Europe. They are darker green than the plains mats, and don't have patches of stones. I have them in 4x3 and 6x4, with and without grids. http://bigredbatshop.co.uk/collections/all/products/grass-design-battle-mat-6-x-4-15cm-grid
