I have 7 of the pattern cabinets in my sewing room, FULL of quilting fabric, with the exception of my flannel which are in a couple 65 qt. plastic totes, I also have about 24 of the same size totes full of fabric other than quilting fabric. The fabrics in the pattern cabinets are ruler folded and sorted by background colors, this works best for me.
I've been quilting since '04 but collected fabric long before then. LOL
