I have a couple of slotted stands that hold the cutting rulers that I use a lot. Others that aren't used as often are in an Ikea cabinet that fits under the longarm. (I store thread for the longarm in two more of those cabinets.) Most of my quilting rulers are also in slotted stands right by the longarm - ones that accommodate the thicker rulers. The round ones are just stacked up, since they would roll out of the stands even if there was room for them there. I've purchased way too many longarm rulers, and find that I use the same ones over and over. I need to expand my quilting repertoire.
