Quarter round molding is a type of trim used to finish off the edges of walls and floors. It is also known as Ovolo, which is a 5-letter word that is often used to describe this type of molding. Quarter round molding is typically made from wood or plastic and is designed to fit around the edges of a room, creating a smooth transition between the wall and floor. It can also be used to hide gaps between two pieces of trim or to add a decorative touch to a room.
