I also like Bonnie Hunter's scrap saver ideas. One that I particularly like is piecing your backs. Use 10 1/2" squares and so they finish 10" making the math of how many do I need to sew together for this back much easier. Nice way to use bigger pieces of fabric and not having to go buy another 6 yards or so for a back. Might be alot of seams if you are going to hand quilt, but shouldn't matter for machine quilting or tying.
