My Best Tip: I use command hooks attached to the inside and outside of cabinets to store my rulers. I also use command hooks to hang my embroidery hoops on the wall behind the door to my sewing room. I use the little metal ones that hold 1/2 lb. just the right size and a couple of them hold multiple rulers.
Like RhondaK, I keep lists of my rulers, owners manuals, embroidery stabilizers, and things needed for a project . I store them on my computer and in Dropbox and can access them wherever I am on my phone.
