i do believe the not storing fabric in plastic refers mostly to the ziploc type bags. and that is for long time storage. i keep my fabrics in clear plastic tubs with lids, each color gets its own tub. theme fabrics get their own also. the size of the tubs depends on space and how much fabric you own. then all the tubs are on floor to ceiling shelves in my work room. i am in there often enough so they get to breathe alot.
