I fold mine on a 6 X 24 ruler. Then fold them in half. No matter what size your fabric is, they are all the same size. I have not yet sorted them in to 1/2 yds, yds & over yet but have thought about it. It took a lot of time & patience but has paid off twice over for me. I also keep an air freshener in mine too so they smell so good when they come out!
