Here's a few early thoughts on terrain for the battle of Blasthof Heath.
The ground and the river will be green paper and blue cellophane held down with double-sided sticky-tape.
The plough will be corrugated cardboard covered patchily with sand and PVA and painted brown.
Blasthof Farm will be a Dapol thatched cotage I own.
The Blasthof Berg will simply be two pieces of polystyrence cut with a hot wire cutter an painted the same shade of green as the paper.
The bridge will probably be foamcore and card, painted to simulate stone.
For trees I have a few Merit items. From the same purchase I also have a few fence-lengths and a couple of hedges that will mark the edges of the plough and the farm-yard.
I'll mark the fordable area of the river with brown paper to represent the muddy bank.
