That is such a gorgeous quilt, I love it. You have plenty of hours in it.
I take my quilt with me to match the backing. (I am a bit fussy) I also like a whole cloth back especially with a quilt with so many pieces like yours. As for quilting do you do it yourself or have a LA'er do it? If you have a trusted LA'er she would know how to quilt it to showcase the lovely piecing.
