I bought about twenty years ago four wooden boards from the local hardware store. Then I glued artificial grass on top of it. Each board has the following dimensions: 23.5´´ & 51.5´´. Because of the fact that I have only four wooden blocks I NEVER had the opportunity to use all four boards at the same time so the usual MO would be to use just two. Only a couple of months ago I turned the backside of the two unused pair of boards into desert boards. Maybe I should get another four wooden blocks and have a weird setup with a harsh change of climate where the grass board meets the desert board. 
A skirmish game where each side has maybe around five models (regular Freebooter´s Fate setup) would work on one of my single boards. Although when you intend to use several large terrain pieces (such as large untraversable steep hills) in a skirmish game you are forced to widen the playing area or else all the models tend to run into bottlenecks.
