Coz my method isn't working! I use a 1/2" artists brush which is accurate but the paint goes on a bit streaky and, when you roller as close as you can when you paint the body of the wall, you always end up having to redo the edges!
I once used a paint pad with 2 little rollers along one edge that you rolled along the adjacent wall but, though it was neat, I couldn't get in quite close enough to the corner or skirting.
So what do you recommend?
