Ok, I tried to show the white lines better. I drew on this with paint and showed the edge of the squares that doesn't show up because it's white on a white design wall. (There is a white line all the way around.) I think what I will have to do is cut some small colored squares for those sides that end up being half the size of the original square. So it will be 10x 11, but on the side with 11 the two outside rows will only be half the size. I don't think I have enough fabric left, though. So I don't know if that will work.
