I sorted mine by type first, flannels, homespuns, 30's, civil war fabrics, Christmas, large florals, and baby fabrics. The rest I sorted by color and stacked them darkest on the bottom to lightest on top. I fold them in half salvage to salvage, then in half the other way so both ends are together. Then starting at the fold, I fold it over about 6 inches, then over again and again till I get to the end. So, it's folded like it was on the bolt, so it's easy to cut off what I need without unfolding the whole thing. The last fold makes it about 6 by 11" and I stack them with the fold side out. I am reorganizing a friend's sewing room right now and she has enough fabric for a quilt shop! It's fun, but is taking soooo long. She buys tone on tone white and cream fabric by the 10 yard piece and I refolded and stacked about 20 pieces! Her shelves are different sizes than mine and most of her pieces bigger, so I'm folding it in about 9" widths. I've done about 1/4th of her fabrics and I've already worked at it 3 or 4 afternoons. When I get done with the fabric on her shelves (2 walls, floor to ceiling) she has fabric in boxes in the hall, in another spare room, and downstairs. I figure I'll be at it for months!!
