Well, the long side did come out as I thought/feared -- still not sure if it will correct itself... but as I say worst case I have 3 corners correct and one corner a little off.
As Bonnie designed with 5 blocks across, the rows stop and end on the same color, adding my extra block means my long sides end on different colors. I can turn the corner just fine, and the one after that... am hoping that by the time I get up top I am matching.
We'll all know in a day or two!
