It was agony to wait, but we finally got upstairs to take pictures. The guy(s) from Reborn Floors spent 5 long days sanding, filling, scraping and finishing our upstairs rooms and stairway. Unfortunately, I didn't get pictures of every individual step because we were trying to stay out of their way, so we'll just have to content ourselves with the after photos.
We decided to finish with a clear finish—Bona Traffic—as we did downstairs so the floors are now quite a bit lighter.
The difference in the big closet is amazing. Except for a patch done by CDR up in the back corner with unattractive knotty wood (upper left in this picture), the wood looks gorgeous. This might be the first time it was finished.
