My stash has been re-folded three times so far. First was a ruler fold. Then wrapped on plastic boards (like comic boards) to store in plastic bins. As needs changed, I went back to ruler folding on the 6 1/2 inch ruler. Each piece is labeled with yardage amount and date. I change the amount as it is used. The stacks are stored in the closet on wire shelving. I do move the fabrics around sometimes when I need to pet them.
The jelly rolls and layer cakes are in plastic bins under work tables. I would love to put them in the closet
