The puzzle is done. 513 pieces and far too many of them were white snow, off-white Ollie's fur, or sun-blasted cedar fencing. I ordered it in late April so it took roughly a month to finish. It would have taken longer but my wife started helping a week ago and that sped things up.
If you study the photo, you may spot a few pieces that look washed out. I suspect that resulted from grandchildren eating breakfast with their dishes or glasses on the puzzle and a few inevitable spills. I was insufficiently paranoid. C'est la vie.
Bravo, Ollie! ❤️
