Get clever with wall storage. Go beyond shelving units, as other options may prove more practical for your needs. Hack suggests wire racks, magnetic systems for tools and a pegboard for sewing essentials.
Dream Quilting room with the wire basket drawers.I have them and they are perfect for fabrics, etc. You can take out the basket to where you are working and easily see what's in it when it's in the system.
closest i've seen to what i want: room for a long arm; sewing station; desk and scrapping area, sitting/tv area, storage (though i'd want mine behind doors/light protected). missing: large cutting/work table and sink area.
