I sort by size, color and style of fabric. I.E. the batiks, the retros, the florals, holiday, ect... Then I also fashion sew for me and my niece. (sometimes others) So those are organized into thier own catagories. Oh and then there is the home and purse fabrics. Also, If I have a certain quilt I have collected/bought fabrics for, it stays stacked all together! Like a kit until that one is finished.
