I like mine stored flat, especially since a lot of them have inserts and 'keys' that would fall out if stood on edge. I really don't like to keep tape on them to hold in the keys or inserts, because it leaves a sticky residue. I have a square of felt in the container on a piece of foam board to keep them completely flat. If I have more than one layer in the container, because some have quite a few different sizes of the same ruler, I also place a piece of felt between the layers so they don't scratch or nick each other. I feel like I am over thinking it. Probably because of the number of containers I have for them on the shelves. It's nice to hear other ideas for storage.
