I want to do a scrappy couch size quilt for my nephew and was inspired by nance-ell's tutorial. I thought I'd use shades of blue with a tone-on-tone white for the center block to brighten it up a bit. Now I'm not so sure. I used 5 inch squares because I have a lot of them and will cut more from fat quarters to add more variety, but don't want to waste the time or fabric if you think I should try something else. What do you think?
