Using this backdrop stand cover is a breeze. Simply pull it over your 7ft round top wedding arch, and it will fit snugly due to its spandex material. Make sure to position it evenly on the arch for the best look. When it comes to cleaning, you can gently hand - wash it in cold water with a mild detergent. Avoid using bleach as it may damage the color. After washing, let it air dry. Don't wring it out forcefully as this could distort the shape. Store it in a cool, dry place when not in use to keep it in good condition.
