Did another, incorporating some of the advice here and it ended up 12 and still cut off those edges.
I also found a blog from a lady that said she had changed the proportions on the block from the book (In her EQ-7), and she put a picture up that showed her outside borders were quite a bit wider and gave a definite 1/4" seam allowance, so maybe I wasn't the only one having trouble?
Also, I've calculated how much fabric I've used so far and it is going to taken and enormous amount to make a quilt.
I surrender and am going to choose a different pattern for these fabrics.
Thanks to everyone who gave such great advice and offered to help.
