I'm now working on the first open cultivation terrain piece. This should be a lot easier than the Enclosed Fields (no stone walls) although I'm experimenting with DAS clay vs Polyfilla on sticks to create realisitic natuaral boundaries (little grassy humps) to separate each field.
So far I've stuck down some corrugated cardboard and some grass and 'wheat', sealed them to the board using polyfilla and painted it all brown.
There will be a 'how to' shortly but pretty easy stuff to be fair!
