Take a look at your wall. There should be a nice open space or two without windows, corners, fixtures, etc. This is a great place to start since it'll give you a chance to get used to your tools. Start with an easy area away from windows, corners, outlets etc. Apply 2-inch detailer to trim at the ceiling and baseboards, apply 12-inch designer to fill in the area, then apply 6-inch accenter and 2-inch detailer to fill in gaps or patch as needed. By the time you finish your easy area, you'll be comfortable with the tools and ready to apply Bella & Birch to the rest of your room.
