Normally my son catches my blocks turned around errors and I am just stuck ripping the flimsy up a bit......and yes, twice can happen.....but he missed the one in the quilt I sent his godmother of her Newfoundland dogs. Lol, she thought it was intentional because it looked like the dog was drooling and loved it! I was humiliated but she was thrilled with it and tells everyone how I customized her quilt.
