Mirabelle...I like the navy too. I think sewing the sashing on as you go I'd a great idea. It changes the entire look of the quilt and you can better plan for the final outcome. That said, I don't have any idea what my sashing will be. I'm using a rusty batik for my FW and a black with my Civil War and I don't want to duplicate those. I'll have t think about it.
