Most of the ones I have seen on Google show the actual quilts, but no measurements.
Using what you mentioned, Bellaboo. to make a 70 x 70 I should need 5 9 patches across, and 5 9 patches down. If I cut them as I need to do, I should wind up with a 70 x 70 inch quilt. Am I right? Then if I put a 2 1/2 sashing and a four in wide border borfrt, I should wind up with a 82 - 83" square quilt?
Maybe I am getting too old for this, but my math has left me.
