A couple of years ago I made a serious effort at organizing my stash--with moderate success. My first separation was fat quarters apart from yardage (1/2 yard cuts and larger). FQ are folded into squares and sorted by color on shelves. I bought several packages of cardboard comic boards for folding the yardage. My yardage is separated first by type---solids, black/whites, batiks, neutrals and lastly prints. Each of these major types is then sorted by color on shelves like comic board 'books'. The last grouping is for scraps smaller than FQ size and is the least organized. I don't precut scraps and leave them intact until I pull them out for a project. They are loosely folded and sorted by color and darks/lights, and are stacked in clear plastic tubs. My whole stash fits in a walk-in closet that I added bookcase shelves to, so it is not as large as others have, but is still too large for my taste. Lastly, I do NOT save those cut off corners, etc that are smaller than 2" square, as I would just never use them---they just go in the trash as I go. Good luck in your efforts! It takes a few days of continuous effort at first, but once you make some progress taming your stash it feels really good!
