Ooooh, is that ever neat! I really like how its coming together! I would probably add a few borders, but that's because the triangles of putting it on point intimidate me...LOL I kind of like it this way, though (straight) because the two different squares that come through in the design *are* on point. If you put your blocks on point, they'll straighten out. Also, I wouldn't do sashing because it will break up part of the design, imo.
