I would probably change the pattern a little and make the center rail 1/2 the block and then the blue 1/4 of the block on each side. I would use an orange batik print for th larger center rail and a tone on tone darker blue batik for the narrow rails.
Pretty orange batik print as a border and bind in dark blue. all in Batik. Use orange for the back. Either tie or quilt using a walking foot.
I love Orange! Every quilt needs atleast a little of it. Just look at my avatar picture.
