I got a small start on things this morning by beginning the first field.
First step was to create a base using styrene and corrugated cardboard. For the styrene, I use plastic "For Sale" type signs from our local big box store. I find them cheaper than buying plastic modeling card online. To create furrows, I pealed off the top layer of a section of corrugated cardboard, gluing the result to the base.
Once that was dry, I coated the entire thing in a dark mud-colored brown.
While the paint was still wet, the entire base was covered in a mixture of model railway ballast and green flock.
Shaking off the excess, this will be left to dry before continuing on.
