(See below for a shopping list and tools.) SUBSCRIBE to This Old House: http://bit.ly/SubscribeThisOldHouse A common decorative flourish for traditional homes, crown molding enriches a space by forming an eye-catching transition between the walls and ceiling. But if your ceilings are high or your room has generous moldings around windows and doorways, a single strip of crown molding might get lost overhead. To get the right effect, you could opt to use a large-profile molding, says This Old House senior technical editor Mark Powers. "But you'll pay a hefty price for large profiles," he says. To lower the cost without sacrificing aesthetics, Mark came up with a way to install a simple L-shaped half beam first, then attach crown moldings to the fascia and soffit for a handsome, built-up appearance. Recruit a buddy to help you make cuts and lift the bulky pieces into place, and in just a couple of days, you'll have pulled off a room transformation that will draw all eyes upward.
