Working on terrain, Orks, Infinity and whatever flits across my line of sight.
Let's start with something that requires minimal effort!
I've had a FAT Mat for a while, and just picked up a Deep cut mouse pad mat so I thought I'd do a quick comparison.
Deep Cut 6x4 mouse pad Swamp mat
FAT Mat 6x4 Barren Wasteland
Cloth: Deep Cut had more accurate pictures of how their mat printed on the mousepad fabric. If you have a vinyl/other version of a mat the mouse pad version will almost certainly be darker than that.
Both have solid detail and texture. Nothing too specific that it would strongly interfere with terrain placement.
Pad material: Very similar. Strong and grippy in both cases. FAT mat is thicker, I'm not sure that it would be noticeable gaming day to day, unless you're constantly dropping resin models all over it.
Overall: I'm ultimately happy with both.
I find the FAT mat a bit odd in that it's not quite desert, not quite 'red sands of mars', it is darker than I was expecting.
The Deep Cut mat is a great general greenery mat and would suit swamps, forests, sci-fi and fantasy. I'm looking forward to getting a lot of use out of it.
