This is something I've been wanting to make for myself for a long time, and a couple of weeks ago, I had a flash of inspiration

The basic idea is to have a large fixed board (or boards) underneath, and then small boards on top that can be re-arranged to make the scenery desired.

I've gone for 2 feet by 4 feet 5mm plywood for my baseboards, onto which I've sketched out a six inch square grid. These six inch squared blocks are to be the basic units of my modular terrain. In the centre of each of these six inch squares on my baseboards, I have superglued a metal washer.

The terrain boards themselves are hardboard. So far I've cut out six inch square, twelve inch square and six by twelve inch terrain boards. To these I have glued paper backed grass flock sheets. I've used the Gaugemaster spring grass product I got from Markway Models in Sheffield - but any similar product would do. Much easier than gluing all that grass onto the boards by hand!!

Finally, I have stuck small pieces of strip basing magnet - I get mine from Hasslefree - to the centre of the underneath of each terrain board, corresponding to where they will connect to the washers on the baseboards.

Works pretty well so far - now I just need to make some terrain that is a little more interesting than flat glass tiles!
