I have a ruler slotted board on my cutting table for those rulers I use daily, I keep my 24" rulers hanging at one end of the cutting table. Those specialty rulers I may use more often than others I have hanging up on pegboard just behind my cutting table and those I rarely use are in a drawer. I keep rulers by a particular maker in separate drawers so I know which drawer to open. Same goes for my quilting rulers, they're in a drawer just under the quilt frame so nearby when I need them.
