Using these pillow covers is a breeze. Just slip your pillow inserts into the envelope - style opening. For indoor use, place them on your sofa, chairs, or beds to instantly enhance the look of your room. For outdoor use, they're great on patio furniture. When it comes to maintenance, spot - clean them with a mild detergent and a soft cloth. Avoid using harsh chemicals as they may damage the polyester material. Keep them away from direct sunlight for long periods to prevent fading. Also, don't machine - wash them unless the care label specifically allows it. These covers are not for commercial use, so make sure to use them in your personal spaces only.
