I've had this new Killings Fields Terrain mat for over a month now.
https://www.killingfieldsterrain.com/Finally had the time today to pull it out of its box and offer some initial thoughts.
I had a couple major concerns when I bought it a few of which proved correct.
My first concern was where and how to store it. It appears thick and spongy in the advert pics and this seems to be mostly true. Its not quite as thick as I had feared but its about a 1/4" thick at the moment. However it was packed folded up and vacuum sealed in a bag and as it airs out over night it may swell up, we'll see in the morning. But regardless if I roll it up its going take up a good amount of space, I'm just not sure where I'll be able to squirrel it away when not in use.
My second biggest fear or maybe it should be my first biggest fear is that it will be a cat magnet. Upon opening it and getting a feel for it, I now have no doubt this thing will be a cat magnet! I may have just purchased 7x5 foot litter box. Not sure how to describe it but the rough texture combined with the soft earthy feel, I'm sure the cats will take turns clawing, chewing and pissing on it. Especially depraved indoor cats like mine.
Because it was packed folded up it has some terrible creases and wrinkles in it. I've packed books on the worst of it. Since the photos were taken I pulled it tight at the corners and added heavier weights at the four corners to try and keep it a little stretched. It has a stretchy property to it that I kind of like and might make it easier to slide books or whatever under to make natural looking hills.
One slight downside is single miniatures have a little difficulty standing up on it and appear to float above ground a little. Its even worse for small based plastic miniatures. However its not as terrible as I thought it could have been and I think its more of a problem for 20mm based miniatures then 25mm and up.
Also for use with large unit type games movement trays will be a must or you'll have to pick up miniatures individually to move them, you cant just push them around the table. Movement trays also help alleviate the floating somewhat.
Hopefully it will air out and flatten out over night and I'll try and take more pics tomorrow.
