The Donna Jordan Tut has the 9 patch put on point. The panels will not be on point. Now she DOES say that with a 10" strip length the final width is 12"....so 8" cut? I am not using cornerstones, but I do want to cut the backside at the 45 to save on fabric.
I've currently got strips of paper all over my cutting mat trying to mock this up. Its not that easy!
