The foyer room wasn't too bad, but I thought I would need to break out the trig to calculate the pieces in the stairwell. Besides the oddball pieces to make, just the location was tough. Fortunately with the built in ledge at the landing, I was able to run an aluminum ladder between it and the upstairs hall with a board on top, giving me pretty good access... though still a bit precarious.
Once again the drywall made a huge difference in seeing how the downstairs will look when finished. I got more walls!!
