I follow the Bonnie Hunter system. I keep lights/darks in 1.0, 1.5, 2.0 and 2.5 strips in plastic drawers. I also have a bricks box, small misc scrap box, I have 3.5 and a 4.5 box. Then my FQ and lengths of fabric are on boards on shelves. Still need some tweaking but I'm pretty happy with this system.
