The ends should be half triangles (at the 4 corners). I just looked up my pattern and the original size was 3" and the side blocks finished size were 6 (then cut in 1/2). That's why I said before, I had to lay the total quilt out before I sewed it and then sewed in diagonal rows. Whole new mind set! :-) It really played with my mind. It does work out though and the quilt I did for a baby girl came out absolutely gorgeous.
