The other day I was having a bit of a terrain clearout (which is also how those brick walls got painted) and I decided to finish it off. So I bashed together a new roof out of a bit of scrap card and some coffee stirrers, stuck it on a piece of scrap foamboard that had been sitting in the shed for over a year and stuck some flock on.
Not the most realistic or detailed piece of terrain ever, but for a total cost of, oh ... £0 ... it'll do. It looks like something I would have failed to produce in my young days.
The grey border thing was supposed to be cut off, but the tower was already stuck together. I'll maybe do it at a later time; it would help with the messy edge. On the other hand, I'm constitutionally disinclined to go back to a finished piece at the best of times, let alone when I've got a crapload of other stuff on.
"Good enough" is a vital concept for the frugal gamer.
