I went to the website just out of curiousity and they have some lovely patterns that would play well with solid colors. Play up the lay out of the colors rather than the print of the fabric since you are using solids. I love those graduated color quilts and some of those optical illusion ones which work so well with solid colors. There was a "to die for" maze quilt on here a few days ago that was solid colors and STUNNING!
Be sure and let us see what you come up with.
