Crown Molding

Nothing signals "finished room" like crown molding at the ceiling line. Pre-primed MDF crown from Home Depot runs $1-3 per linear foot. A 12x14 room needs about 52 linear feet — so $52-$156 in materials. The challenge is cutting accurate compound angles on an inside and outside corner. A coping saw and patience produces tighter joints than trying to miter both pieces. Flexible caulk fills small gaps. Once painted, nobody can tell if the joints are perfect or merely good. It's the architectural detail that separates "apartment" from "home."
