My cutting rulers are hanging on a nail (wall) at the end of my cutting table. My quilting rulers are hanging on a peg board (behind where I stand) at my longarm. I place the rulers that are from the same set (designer) in a pocket protector to keep them together. For example: Lisa Calle rulers are in one pocket protector, Linda Taylor rulers are in another pocket protector. Etc. etc.
The rulers I use the most (example: Natalia Bonner’s 4-n-1) hangs on its own peg with 3-4 other favorites.
