Not sure if anyone has used Terra Tiles ( https://rainnstudios.com/ ), but I got some on a whim.
They're pretty good terrain, but I find I'm having trouble with keeping them flush against each other because they slide around tables a lot. I've tried putting them down onto a mouse-pad like surface, as I have some starfield mats I use with Armada and x-wing, but they still slide around a bit.
Anyone have any solutions or thoughts? I mean, I suppose I could just glue them all down onto a surface, but I feel like that rather goes against the whole point of them being modular.
