What shapes and sizes do y'all make your scraps? Do you find certain widths best for strips? How do you organize them? My scraps have been "organized" by being thrown in one huge bag and, once long ago, sorted by color--dark, medium and light. But the other day when I wanted to do a scrap quilt in strips, by the time I got 2" strips cut I was out of energy and time! Now I think I oughta cut them into useful sizes as I go and then they'd be available when time and energy converge. But, what's most useful? I do machine piecing and no appliqué, if that matters.
TIA
