I couldn't find the 'mistake' had no clue what you were talking about till I finished reading...obviously the eye gravitates to the photo first.
Hey if you can spot a mistake from a train racing 100 miles an hr at 50 feet away, THEN there is a mistake. No one is going to see what you think is a mistake, so don't point it out to them.
The 'heart' quilt is lovely. really.
