Most homes, especially older ones, have some irregularities, especially along the ceilings. Often, these homes simply aren’t square or plumb. Most people would never notice it, but large pieces of furniture can sometimes highlight these irregularities. The flexibility of most crown molding means that it can be bent slightly to account for these irregularities and lessen their visual impact. Crown molding is an excellent way to camouflage inconsistencies and provide the illusion of even, regular ceilings.
