I don't machine quilt but I have tons (relatively) now of other stencils. Not sure if yours are commercially produced or not. Mine are and all have holes at one end. I use a circular belt hanger that I then hang on a hook on the back of the door in my sewing room. Not overly organized, per se, but they are controlled and I can easily look through them and then just grab the bunch in front of the one I want and then replace the unwanted bunch back on the belt hanger.
