I had to search, and I did so before reading any more than the title of your post. So, I started at the right top and looked across it until I saw what I think is a turned 4 patch. It's on the top near the left corner. Then I read your words. Sorry to point it out, but I am pretty sure there are 2 mistakes in this top. I'm good at spotting them because I have made so many myself! If you make two it's more likely that people will think it's intentional.
