I store all my jelly rolls, layer cakes, charm packs etc by cut. Fat Quarters that are a collection are kept bundled and since 80% of my fabric is Batik, I have those sorted by cut and color. The remainder of my quilting fabric is sorted by color so thats its easy to pull from. I spent about 6 weeks towards the end of 2019 getting my studio and my fabric organized and not only does it look better I can actually find what I need. I also sold off about 40% of my stash and was very happy with the end results.
What works for me may not work for someone else, its such a personal choice as we are all wired differently.
