I'd done the geomorphic terrain board thing in the early 80's and as terrific as it can look when well done, I knew I didn't want to go back there. I have often used a cloth laid over shapes but that method doesn't work well with single figures as they have trouble on the slopes so I have also often used a painted tabletop with hills placed on top.
The decision to stick with multi-figure bases for most of my collections coupled with the appearance of hexes on my tabletop meant that some form of cloth was in order for regular games. Having calculated the cost and effort to do the latex and flocking on cloth thing, I decided I wasn't up for either aspect. My next choice was a piece of appropriately coloured cloth with some over painting. My old one is 15 years old now and faded and anyway it is was in fall colours and I'm ready for the sort of rolling green hills that I'll be living amongst in a month's time. I finally admitted that I was not going to manage a fabric shopping trip to Halifax so hit the local hardware store for a canvas drop cloth and a quart of green paint. (BTW When we went metric, why didn't they resize the quart paint cans to a litre instead of 870ml? Who can remember to ask for 870ml? )
Stage 1 a mottled green. Now to add yellow, brown and darker and light green touches.
The drop cloths came in two sizes, too big and too small. I opted for too big, 10 ft x 11 ft. Not quite big enough for two since a 5.5" width would be a tight fit for draping over hills and wouldn't work at all on a 6 ft wide table. I could leave it as is to fit over the 6ft x 10ft tables at Cold Wars but that would leave a lot of over hang to trip on during the other 99% of games. My current thought is to cut a piece 7ft x 9ft and use the offcuts as templates to mark woods, towns etc and to make a gridded playing service for a portable wargame.
