Terri, I've found discrepancies with the Go cuts too. I think it's best to use them when all the blocks in the quilt will be the same. Then exact size doesn't matter as much. Your block is still striking!
Hope your hubby does ok.
I am so sad since learning yesterday that my all time music HERO, Brian Wilson, passed away. I loved that man and always will. Very sad. What a gift he was to us.
