Roofs.

Following on from my discussions with Allan Downes, I thought that I must put his suggestions into practise.
There followed an amount of time spent marking out card for tiles the right size- or so I thought- and an equal amount of time trying to cut them out.
The best laid plans eh? What transpired was a lot of irregular shapes, but, not one to waste a few hours work, I decided to give it a go anyway.
The result, for this building is particularly pleasing  (to me anyway) and having looked at similar aged buildings to me it looks right.
If that is good enough for Allan Downes- who am I to argue! Just need to find some Terracotta paint now.
