I organized my stash last year simular to this method, only I use corragated cardbord. I saved boxes from the grocery store and mail deliveries. I started out by buying a stack of the boxes they sell at Sam's club. Then realized I could ask at the grocery store and walmart for theirs. I marked one of my rotaty cutters "cardboard" and used that to cut 8 x 11 inch pieces and folded my yardage on that. I cut 5inch squares for my fat quarters. All of my yardage is on shelves in my sewing room (the cardboard bolts from Joanne's are to big for my shelves). I sort my material by color, holiday prints and neutrals.
