I don’t think this is exactly what the sub category was set up for - but it’s immediately where my mind went. Sorry!
Any ways, I love seeing home made terrain for table top games. I go through frenzied phases where I make a bunch of it then, generally, never use it. I find it too restrictive when running RPG games, and I never have as much fun playing skrimish/war games as I think I will, so generally the terrain I make is wasted. That said, I love making it and seeing other people’s DIY stuff.
Maybe we could share our terrain Arts and Crafts here?
Here’s some Sci Fi terrain I made a while back. I got a bunch more in the shed that I never ended up using - maybe I’ll finally paint up those 15mm sci fi minis I got and do a photoshoot.
