I've been folowing the Bonnie Hunter method mentioned above. If I can, I cut either a 5xwidth of fabric strip or a 2.5 by width of fabric. If I can't get WOF then I cut either 2.5, 3.0, 3.5 or 4.0 squares. Then, sort by color and put in a plastic bag by color and all the same sizes in a plastic bin. I am looking forward to making a quilt that I don't have to cut ANYTHING for. I will just use my pre-cut scraps. Of course, ya gotta like scrappy for this to work!
