Step 4: Hang Molding
Measure 1 inch from the bottom of your crown molding or ceiling, and lightly mark the wall with pencil. Line up the top of the molding with your mark, and tack molding in place with finishing nails. Hang the rest of the molding using a level as you go. Punch the nails into the wood with a nail set, fill the holes with nail-hole filler, and touch up the paint.
