I was wondering if anyone knew of an easy-to-sew pattern (preferably one that may fold so i can store it when i don't need it, but it doesn't have to fold) for a shade canopy that attaches onto one of those radio flyer wagons. The type of wagon i have is called a radio flyer pathfinder. It holds two children face to face with the seats that flip up. And if there is a pattern out there, what is the best kind of fabric to use to block out those dangerous UV rays? Thanks in advance for those of you who can help me out.
