I also started the Sarah Johnson quilt at camp. I've had the pattern for years, but didn't feel I had the time or expertise to attempt it. I got most of the middle medallion finished at camp and began working on the 172 star blocks needed. As of today, my star blocks are done and my applique blocks are prepped. I should be able to start assembling next week. I included the second picture with my hand so you can see the small scale.
Here is a link to the pattern and some background on the quilt.https://www.hooplapatterns.com/shop/Shelburne-Museum/p/Sarah-Johnson-Quilt-pattern-x20241186.htm
