We like to treat every room in our house like a gem, so recently we decided our little hallway should have a painted pattern on the ceiling. There is a stairway, two bedroom doors, a bathroom door and a large opening into the living room in this space and the walls are a medium shade of aqua. We chose a soft, light aqua and orange to coordinate with the living room.
Marking and taping off the design was the most difficult. After that it was just a matter of filling in the spaces with paint. A word to the wise, you should peel the tape off while the paint is still wet to insure a clean line that doesn't pull off more of the paint than is desirable.
