I base my sorting on the way one of my favorite quilt stores is organized. I can't handle sorting only by color, too unorganized for me. I sort by theme (civil war and 18-19th century repros), 30's, Asians, neutrals, backgrounds suitable for redwork or other embroidery, etc. Within the catagory I may sort by fabric line or color. I ruler fold and the folded fabric goes in wire closetmaid drawers on frames. I do have two drawers that are blues and whites and white and blues, they are mainly repros, also. Likewise a drawer that's reds and red and white. Batiks are folded (but not ruler folded) and stacked in the closet on wire shelves. There is never going to be enough room because stuff grows to fill the space available. This works but I would like to replace the drawer units with Ikea Besta cabinets with doors. It would give me more storage, reduce the footprint on the floor and use more vertical space. I even went so far as to figure the number of cubic inches I would gain. It will have to wait until we re carpet the house in a year or two. I'm Not willing to breakdown and move things out of the sewing room twice, even thougth it's only 10 x 11.5 feet.
