Using this backdrop cover is easy. First, find your 5ft round top wedding arch. Then simply pull the cover over the arch until it fits snugly. It's double - sided, so both sides of the stand will look great. When it comes to maintenance, spot clean it gently 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 too hard when drying. Let it air dry naturally. Store it in a cool, dry place when not in use to keep it in good condition.
