Just as the right tie can really make a suit, or a well-chosen accessory can add some pop to an outfit, molding can turn a plain square room into a true showpiece. When you're considering how best to add trim to any room, don’t just think ceilings and floors. Trim works well along the middle of a wall, three-quarters down from the ceiling, around windows and doors, or along the edges of architectural features such as built-in bookcases or recessed panels in walls or ceilings. When it comes to trim styles, you are really limited only by your imagination: You can go with chunky, wide, or layered trim for a bold look, or opt for delicate, narrow trim to keep things elegant. Plus, you can buy molding in a variety of materials, from paintable, stainable woods to lightweight, plastic molding that doesn’t need finishing.
