You did a wonderful job and came out with a beautiful quilt. But if you don't want to put that much quilt through the DSM again, try quilting in sections. This is NOT the same as quilt-as-you-go (QAYG), and although you do need to put some thought into how you are going to divide up the sections, for the most part you just piece your blocks and sew them together as you normally would. Marti Michel has a great book showing many different methods to use.
