Using this wedding arch cover is a breeze. Just take the two pieces, the top and the bottom, and pull them over your 7.5ft Crescent Moon Metal Wedding Arch until you get a nice, snug fit. For best results, make sure the arch is clean and dry before putting on the cover. When it comes to maintenance, if the cover gets dirty, you can gently hand - wash it in cold water with a mild detergent. Don't use bleach or harsh chemicals as they may damage the spandex. After washing, let it air dry. Keep in mind that this order is only for the cover, so you'll need to provide your own arch stand and any other accessories. This cover is reusable, so after your event, carefully remove it, fold it up, and store it in a cool, dry place for future use.
