No help here but really do like that fabric. I liked the shadowbox pattern.

i have to make a modern quilt for my son and daughter in law. using blues and gray.
love the fabrics and your idea is perfect. simple and elegant. i would like the tree fabric in strips at least 6 in.
this is an option too. http://www.ttfabrics.com/projects/lux-blue-fancy-that/
