I agree with Friendly Quilter- perhaps you might consider using the solid black as a narrow border or as the binding to tie the quilt together, especially since you do not have all of your blocks made yet. Looking great so far, Be sure to show a picture when finished. One way you can have an idea as to how several blocks look together is to use a mirror and this will reflect the blocks or use a camera. I always lay my quilt blocks out and take pics, then see where I need to make changes. Since I use my digital, I can view them right away and not have to wait for prints, or just viewing through a camera lens. My camera also helps to see how I had a pattern laid out in case I can't get it completed right away, I also use the small colored dots - many use on garage sale items and pin these to blocks for certin rows etc. just a few hints that work for me.
