I have a vertical rack that I hang on my wall just above my cutting table. I also have a flat, horizontal rack that is next to my cutting table. These hold my big and square rullers (and a couple of weird shapes such as the FlipFlop ruler). My small ones and my specialty rulers are kept in a plastic shoe box on a shelf. I have more rulers that I know what to do with, but I really have this thing about tools - the more the merrier.
