I need help on how I can paint my walls and not get it on the ceiling. My exterior walls are 10 ft. high but rise up to 14 ft. At 10 feet I have alcoves (I was told plant shelves) which go back about 3 ft. then the walls rise up another 4 ft.at the highest point. These are in my living room, dining room, kitchen and hall. I want to paint but even if I use a 12 ft. ladder, I can't reach back far enough to paint and if I use a roller I can't reach to tape the ceiling off. Anyone have any ideas?
