Using this backdrop cover is a breeze. First, make sure your 5ft round top wedding arch is set up properly. Then, simply pull the cover over the arch until it fits snugly. It's double - sided, so you don't have to worry about which side to show. When it comes to maintenance, spot - clean it with a mild detergent if it gets dirty. Avoid using harsh chemicals as they might damage the shimmer tinsel spandex material. Also, don't wring it out; instead, let it air dry. Store it in a cool, dry place when not in use to keep it in great condition.
