I keep my stunt kites in PVC tubes. And my less expensive fishing rods that didn't come with their own cases. I also built a six foot frame to hold one of those blue tarps - I use for a light screen for my telescope - to block neighbor's porch lights. When the kids were little, some one inch thickwall PVC with paint made some mighty fine Star Wars light sabers (unfortunately, these were stout enough to do more damage to their playmates than actual light sabers would have!)
