Using this arch cover is a breeze. Just slip the two pieces - the top and bottom - over your 7.5ft crescent moon metal wedding arch. Make sure to adjust it for a snug fit. Remember, this order is only for the cover, so you'll need your own stand. When it comes to cleaning, you can gently hand - wash it in cold water and let it air dry. This will help keep the spandex in good condition for future use. Also, store it in a cool, dry place when not in use to maintain its quality.
