Using this backdrop stand cover is easy. Just slip it over your 7ft round top wedding arch, and it will fit snugly due to its pullover design. Make sure to smooth out any wrinkles for a perfect look. When it comes to maintenance, you can hand - wash it in cold water with a mild detergent. Avoid using bleach or harsh chemicals as they may damage the spandex material. After washing, gently squeeze out the excess water and let it air dry. Don't wring it out as this could cause the cover to lose its shape. Also, store it in a cool, dry place when not in use to keep it in good condition.
