I stored all my fabrics in plastic totes as I lived in Florida and I was more worried about moisture and bugs down there. The totes were in storage for 4 years with no visible damage I could see. I still have some fabrics in totes under my quilt frame for lack of anywhere else to put them so its been 10 years for some of them. I do bring them out to check them and refold them so they don't get a permanent fold line. These are mostly dress fabrics too and not cottons for quilts.
