If I can;t keep everything in it's place or hidden behind closed doors -- out it goes. I donate anything I don't want or will use. I have kitchen cabinets in my sewing room, bought especially for that use. 90" countertop ontop of the base cabinets. I have two large closets with the wire shelves to store large, medium and small amounts of fabrics on. I store rolls of poly batting, large bag of scrap batting, rubbermaid storage boxes and small boxes of scraps, ironing board, sewing machine table. I still have a couple of empty upper cabinets. I now have a perfect for me sewing room.
