I've learned to plaster a wall. Took me a while. Christ, the first few times I needed to belt sand it. Now, I'm pretty confident. Did a pair of alcoves recently and they were flat flush. Perfect. No filler needed. Can't pretend I could earn a living off it, but I've sure as hell learned enough to take the mystique out of it. Think I'll be building the extension myself. Hired a digger recently, piece of piss. 'It's so difficult to operate a digger.' Is it my arse.
