Thanks all

In reply to the questions:
I’ve moved away from hilly boards to flat boards, as I now tend to place terrain on top, which means I can use the board for multi periods. So the grit is very mono indeed, for a level surface that can take extra decor in the form of trees, buildings and even hills.
One thing I really dislike doing, whether minis or terrain, is prepainting. Obvs I planned out the terrain but I enjoy a more organic build process. I think that if I prepainted, I’d never finish. That said, these tiles are pretty simple so I don’t expect any issues with painting.
