I used to do mine by color, but now I reorganized and sorted by yardage, under 1/2 yard, exactly 1/2 yard, 1 yard, up to 4 yds, and then 4 yds and over. I know I need 4 yards for a single bed, and sometimes will pick out a back before I pick out the colors for a front. I know it is backwards, (back, colors and then pattern) but it works for me.
