I vote for the D9P for a scrappy quilt!! I also learned about them here and just love how a scrappy D9P looks. If you don't have enough large pieces for the squares, just sew a bunch of the scraps together and then cut the squares and proceed. It would make it nice and scrappy.
I am making scrappy D9P quilts for my 10 mo. old grand daughters and appliqued butterflies, and other things on some of the big squares after the quilt tops were sewn together. they are turning out quite nicely.
