I recently went through a number of boxes, washed, ironed measured folded and stored fabric from those. I cut squares from index cards and pinned to yardages, even large scraps were measured and tagged. I have 1 yard lengths on one shelf, 1/2 yd on another and over 1 yard on big bottom shelf. I had a couple of pieces that were 6 and 8 yards. 1/4 yards are in small plastic boxes and smaller bits in a little bin. It works well until my "quilt inspectors" decide to romp through and knock stuff about.
Now I've found some more "stashed stash" in the garage.. here I go again!!!
