Throw pillows are those decorative squares that so often are found on chairs, couches or tumbled into a corner in a living room. They can be patchwork, embroidered, brocade, cotton or linen. If your couch has a floral or striped pattern, throw pillows in solid colors can complement the design. If your couch is solid, then make your throw pillows something that will stand out against that monochrome background. Throw pillows can deliver a message or they can be commemorative.
