Using these pillow covers is a breeze. Simply slide your pillow inserts into the envelope - style opening and place them on your chair or sofa. For indoor use, they'll add a coastal charm to your living area. Outdoors, they can withstand the sun and light rain thanks to their water and UV resistance. When it comes to maintenance, spot - clean them with a mild detergent if they get dirty. Avoid using harsh chemicals as they may damage the fabric. Since they're mold and mildew resistant, you don't have to worry much about them getting ruined in humid conditions. Just make sure to keep them dry if they get wet. And remember, these are for non - commercial use only, so enjoy them in your home.
