I`m hopeless with terrain, I freely confess I just don`t have a clue or the time of patience for those wonderful constructions you see in the wargames press of online.
We have been renovating a house we own, part of that renovation was insulating an outside cupboard to protect the internal walls from damp. I used insulation boards, very handy and easy to use, there were of course left over bits and off-cuts. I decided to try and build a few simple hills for our tabletop. Nothing fancy, cut to shape glued to hardboard bases, painted with several coats of magnolia and terracotta paint, then stained with a dark wood-stain. Simple, cheap and only took about 48hrs (including drying time). I`ve included a couple of figures and a vehicle for scale.
