I've also gone round putting masking tape along the ceiling and kitchen cupboards etc., ready to start painting those walls. This is following advice from other people, rather than my usual approach of either holding a piece of cardboard against the edge or saying "Ok, I'll be really really careful this time ... crap!" (On a related note, I've been thinking about getting hold of "Operation!" for my next silly games party, but I suspect that my artistic friends will easily beat me.)
Since people seem to like photos, here's today's progress.
The kitchen/hallway ceiling, complete with masking tape:
The WC:
It belatedly occurs to me that there's a certain Oompa-Loompa quality to it, but never mind...
Actually, I've also noticed that the new paint in the bedroom/WC does reflect the light better than the bare plaster did, so it almost looks as if the light is on in those rooms, even when it's not. Radio-active paint: it's the choice for the final generation! Now all I need to do is encourage a spider to build a web in the corner somewhere...
