If it were mine, I would do a Pam Clarke leaf motif in the white part to keep the feel of the wilderness, easy enough to do, then in the print blocks, just and easy loop d loop or something as such or even a side to side wave in the water ones, clouds with the eagles, etc. and then for the sashing, would just do a leaf it design, a twig with leaves coming sparatically on each side to add interest but keeping it simple. Then a piano keep border or you can follow with the leaf feather idea in outer border. Simple but effective.
