Will you be storing them on shelves or in bins or drawers?If i were storing on shelves and rolling the fabric, i’d bowtie each roll with a selvage strip, and when the fabric was one layer deep across , I’d put in a styrofoam board cut to fit. Essentially make more shelves that will divide the stash. I woukd do it by colir. Dollar store has big poster size styrofoam board that are easy to cut.
