I love your quilt so far the colors are really pretty, I think that I would try and cut a triangle in black to fill in the corners. I think that maybe you just need to walk away from it for a little while and then figure out what you want to do. I know that you will figure it out and it will be beautiful when you are done. A black,white and red quilt is on my to do list. Post pictures when you are done. HUGS
