Finally caught up and have all the blocks done from the first three rounds. Pic below are the last 4 blocks complete. The sun, the schoolhouse, the hearts, and the 12.5" block from the Feb 1 set.
I was going to use a blanket stitch on the hearts, but in the end I decided on a simple satin stitch. I also used a satin stitch to attach the white top to the sun, but I machine pieced the bottom "pie" to the bottom of the sun.
