Hi,
Sorry this is a bit of a shameless plug (well I do feel a bit ashamed). I've come up with a design for base-boards which allow the board, and any attached terrain to be folded up, transported or stored very easily. I've used the boards in my North African terrain, which appears in some of my other posts. There's a short video of it folding away and a picture from the KickStarter project below.
I hope some of you might be interested in the KickStarter but I'm also really interested in any comments or other feedback you guys might have about the base-board idea. There's also a lot of information about the boards on my website.
Sorry again about the plug but I hope this is something that people might be interested in.
Cheers.
