Using this cover is a breeze! Just slip the top piece over the top part of your 7.5ft Crescent Moon Metal Wedding Arch, and then put the bottom piece on the lower part. Make sure it's pulled down snugly for a great look. Remember, this order is only for the cover, so you'll need to have your own arch stand. When it comes to maintenance, it's very easy. You can gently hand - wash it in cool water and let it air dry. This way, it'll stay in great shape and be reusable for your next event. And always keep it away from sharp objects to avoid any tears.
