SuzSLO, I love those subtle blues and greens. I almost bought some of this line (but managed to resist). It doesn't look matchy-matchy at all, and personally, I would hesitate to bring other colors in and spoil the effect of these lovely shades. I checked the photo of the quilt with sashing, and I like this lattice look more, if you don't mind the effort of matching the x's. You could probably find more of these fabrics if you wanted to invest the money and time to make it bigger, but it would be lovely sewn and bound as. is.
