Thanks. I can't do black on the bottom because I'll be hand-quilting each block. I'll be machine sewing when I zig zag around the melons, but if I've already got hand quilted burgundy stitches showing, then I want burgundy on the back zig zag as well. Anyway, I'll do a sample block on the quilt itself and I should be able to tell from that. Quite often my mental image of something and the reality of it are different, so I have to wait and see.
I'm from B.C., too, once upon a time.
