It is a very pretty quilt. If you are referring to the inside of the quilt as your 1-1/2" squares, there are only sets of 6 and 5 squares. I don't think you would need to sew all 28 together in one set. If you make 2 sets of 5, and 4 sets of 6, you will fully utilize your 28 sets, or different fabrics (if that is what it is). As the each "elbow" in the quilt has a set of 6 and of 5, you'll need to remove one square off one of your sets of 6 to get your even sets.
