I'm doing mine in scrappy 30's. It's kind of slow going because when I put my first two block together with completely random scrappy neutrals, I didn't like it. Mostly because 30's prints are pretty busy to begin with and it just didn't look good to me. So I decided to do more of a 'controlled scrappy' within each block and I like them much better. Also, I'm using blues in place of the gray.
