Very nice, QuiltE!
When doing mine, I was annoyed when (a) the perfect combination of fabrics turned out to be not so perfect and/or (b) the photos lied, no matter how hard I tried to get a good picture. Occasionally, a block looked better in the photo, but usually it looked worse.
Toward the end, I did re-make a few blocks, using either part or all of the original pieces, but shifting them around. The last thing I did as I was putting the quilt together was a total do-over (with different fabric) of the railroad block.
The whole FWS was very educational, both in terms of color value and how to do the most painless & accurate construction.
