Here again is the map of the battlefield. Each successive lighter color represents a 20-foot increase in height.
Here is the battlefield in foam board laying on top of the vinyl mat. Little fighting occurred in the low areas, so I cut out in foam board only the highest points on the battlefield. The road is cardboard cut from a case of soda.
I then painted the foam board with a muddy mix of acrylics and sprinkled flocking material on the paint while it was wet. Then -- trouble. The edges of the foam board curled up forcing me to take a new approach.
