I used Rustoleum spray paint for a solid primer. It's easy to twist the umbrella to create ombre color swirls. Wait at least 24 hours to give it time to settle, release gas, etc. I sealed my samples after 12 hours and they stuck to themselves and peeled off the paint when I opened them. Easy enough to recolor and hide. I also used Apple Barrel paints to add patterns like clouds, geometric patterns, sunsets, thunderstorms, and flowers. I also sewed artificial flowers. I don't think they will keep the rain out when I'm done but hanging from the rafters in our open Covid worship room they looked spectacular. They cope very well with the strong winds in our wind tunnel. The installation used tie-down straps on the handles and 50-pound fishing line from the ribs to keep the wind from blowing them away.
