Using these backdrop covers is easy. Just pull them over the 6.5ft or 8ft stands of your wedding arch. Make sure to smooth out any wrinkles for a perfect look. Remember, this order only includes the covers, so you'll need to provide your own stands. When it comes to maintenance, spot - clean the spandex covers with a mild detergent and let them air dry. Avoid using harsh chemicals as they may damage the fabric. Also, store them in a cool, dry place when not in use to keep them in good condition.
