Open floor plans with all hardwood floors sometimes appear too expansive, almost cavernous. It can seem a pity to cover beautiful wood, but area rugs placed over wall-to-wall wood floors can enhance a space.

"Area rugs help to define a space and should be sized to fit furniture and/or seating groups, such as a living room, dining room or den," said Bruce Wentworth, of Wentworth Inc.

He says to put a sofa, coffee table or pair of chairs over a rug to form an aesthetic and functional seating group. "Spaces will feel larger when rugs are used because the differing areas will be perceived as separate and unique spaces," he said.

Allow the hardwood to be exposed around the perimeter of the rug to provide contrast,

"One rule I always try to follow is to have at least the front legs of each piece of furniture on the rug," said Paola McDonald, of Creative Elegance Interiors. "You don't want your rug to look too small or out of scale with the room or the furniture. This ensures that it won't."
