Using this backdrop stand cover is easy. Simply pull it over your 7ft round top wedding arch to get a nice, snug fit. When it comes to cleaning, you can gently hand - wash it in cool water and let it air dry. Avoid using harsh detergents as they may damage the spandex material. Store it in a cool, dry place when not in use to keep it in good condition. Also, be careful not to pull it too hard during installation to prevent any tearing.
