I think Martha Stewart would approve of kites as a design choice. They suggest summer, the outdoors, and carefree living; they're colorful and lightweight; they cost much less than a good painting; and they can be taken off the wall and enjoyed from time to time.
Here's an old Premier kite that was a faithful friend at the beach for years. Now it flies all day long above the door to my backyard (in poor light, unfortunately). I'm not a craftsman, but I've got some ancient beach kites that could live out their retirement as some kind of wall hanging or craft project. I think hanging more than one from the ceiling might be going too far. ;-)
