I started painting terrain for my FLGS so that we can have good looking battles. I've got one table's worth done so far. Nothing fancy, just highlighted grey on the top and mud brown on the bottom. I used Liquid Nails mixed with fine gravel for the basing, which gives it a rough look that models will still stand on.
I should have some half-decent shots of the whole set next week, hopefully with some well-painted armies to go with them!
