throw pillows, decorative pillowsI just bought a new couch for my small living-room in my house. As an interior designer, I need to have my house decorated. One good idea to decorate a couch in the living room is to add some throw pillows. There are various patterns and materials for its cover, from velvet throw pillows, heavy textures, solid colors and floral pattern. The best way is to mix and match wit the theme color of the room and the couch.
