I came upon this article on an evidently semi-defunct gamer’s blog, but it struck me as an insanely sensible, not to speak of workmanlike bit of modular terrain I might look into making myself: http://hachimanstoychest.blogspot.com/p/interlocking-modular-terrain-tiles.html
Reminiscent of some things I’ve seen others do around here, and I thought it might get some thinking/discussion going. By the bye – this is aimed at Thaddeus Blanchette, here – I seem to recall a bit on making flexible road segments using silicone glue. Where did that get off to?
I made a couple of tiles exactly like that, except I didn’t put mdf board under mine to keep them from warping. Good idea, that. On the other hand, mine were reversible: yellow on one side and green on the other.
This is an excellent way to make terrain tiles. I eventually went with a cloth draped over them, however, because it’s even more flexible.
