The battle of Narwa game a friend and i ("friend" is a bit strong more someone i haven't manged to shake off.lol) are putting on needed a big hill for the Germans to use as a HQ.It's hard in the pictures to get a sense of how big this piece is but one of the photos has a king tiger in it for scale.
Made from 3 polystyrene sheets pva glued together,then hacked about until hill shaped,with ployfiller/sand mix spread as a road surface.
The pitted rough area's on the corner was created by spraying it with battlefront spray paint which starts to eat the polystyrene away (i don't wish to talk about how i found this out many years ago,it was a sad day and i have moved on) when it eats enough away that you think looks good press a very wet towel onto it which will stop the paint eating away anymore of the polystyrene.
Painted using americano paints cinnamon brown adding more and more light grey for highlights.
