Using this wedding arch cover is easy. Just slip the two pieces - the top and bottom - over your 7.5ft Crescent Moon Metal Wedding Arch. It's a pullover design, so it'll fit snugly. When it comes to cleaning, you can gently hand - wash it in cold water with mild detergent. Don't bleach it. After washing, let it air dry. Remember, this order only includes the cover, so you'll need to have your own arch stand. Also, keep it away from sharp objects to avoid tears. This cover is reusable, so take good care of it for future events.
