I'm working on some home construction and have encountered an angle problem that's made me tired.
I have a sloped ceiling (45 degrees) that continues around a corner (90 degrees). Now I want to install furring strips (28x70) and then put up drywall. I've tried miter sawing the panel so that the boards meet nicely at the corner point, but I just can't get it right.
How should I approach installing furring strips and drywall in such a corner?
