I couldn't have said it better myself. In my first rag quilt, I used 6 1/2" blocks with a 1" seam, leaving 5 1/2" finished blocks. The most recent rag quilt I made, I used 8" blocks with a 1" seam and it was 6 rows by 7 rows. I used flannel in both of mine. I used larger blocks so it wouldn't take quite as long and so you could actually see the print in them a little better. Good luck on your quilt! :D
