Hey Steph...the maze is amazing! Is there really a "way out"? I see your problem with the border. My suggestion would be to not make it as wide, maybe the same size as the blocks that are in it. And use a matching color, not black as I think that would over power the black squares in the quilt and make it not look so much like a maze thereby taking away that effect. Use a medium color that would not take away from the maze the black is creating, but still be in sync with the colors that are there. I see a maroonish color and a green that might be good. To light a color would, I think, make it look like the maze is just kind of like left "open", like "I've come to the side...now what?" But boy howdy, you put in a ton of work and it does really look great! I couldn't have done it!
