The way you organize relates well to the quilts you want to make. One of my favorite scrappies is called square vestibule, so I have baggies of 2.5" and 5.5" squares as well as 2.5 by 5.5" strips (2 of the latter per block).It is amazing how fast a precut quilt goes together. I also like to add star points to the ends of the strips, making the smaller squares into star centers. Of course there are lots of other uses for those shapes. Twice, I have just finished a bed sized quilt only to hear of a great need for an immediate quilt.
