Lo and behold, there was a sight for terrain mat hunting eyes: 30cm square interlocking foam mats, topped with a greenish teddy bear fur type material.
I grabbed four to take home and check out (I could always use them as an actual mat, I said to myself...). They looked OK, so I went in again to get another sixteen (the final sixteen, it so happens!) so that I can do a 4' by 5' Lost Battles board.
|In their packages...|
|Set up for Lost Battles' size|
|With a different filter which is closer to the actual colour of the material.|
