...or should that be 7 or 8?
I've managed to move things on a bit. All boards now have a grass mat covering, the river has been "levelled" out with some thinned down filler, poured on and "blown" into place; hard work that!
Roads have been cut out of the grass mat and textured, as have the river banks. Textured "goop" made with random amounts of sand, PVA and dark brown emulsion, liberally applied by 1/2" paint brush. I've given this two highlights, dry-brushed on, with probably one more lighter shade to follow.
Still lots to add, including varying shades of static grass in random patches. I also need to come up with a believable effort at a river. Hopefully, the roads will line up!
I'll probably also add two more boards to increase the table size to 6' deep by 8' wide.
