Mary,
I love your r/w/blk quilt and I too am a fan of D9P I made 2 of them this summer. Actually one I only helped with it was my neighbors daughters wedding quilt and it turned out lovely.

You have lots of great suggestions here for choosing colors.
I actually probably enjoy choosing my fabrics more than any other step of quilting. I just love to go to the quilt stores and play for hours pulling fabrics and trying different ones together or now in my stash.
I will be doing the fw's quilt on this board in Kansas Trouble fabrics these have a lot of the colors like you said you like and I did purchase various lines of them when I started collecting them a couple years back so they all go together very well.
Have fun and enjoy the process,
Muriel
