I'm another one (Welshman that is).
The problem is that the top of those book cases is over 10ft above floor level. The fiddle yard baseboards are 3 ft wide. To reach the top shelves I have to stand on the top level of a stepladder. It's precarious and I always worry about dropping something 7ft onto the layout, not to mention falling onto it myself. I am not confident of being able to get anything, however lightweight up there, and to ensure it stayed where it was put. I think the fact that I would then have to remove the boards when I wanted to get to books, which I shall need to do makes an accident waiting to happen even more likely.
Gilbert You wouldn't need to go that high with a backcloth because you could crop the picture down to where the backcloth finished.
