To involve less piecing you could do the dark blue strips as
an 8 x 2 and do the corners like you do a flying geese. You could also do the light blue outside piece as a 6 x 2 and do the corners the same. Add a light blue to the end of the strip for the side. Make a 4 inch pinwheel for the center. Of course you would have to add the 1/2 inch for seams. Just a thought as the bigger the pieces are, the better mine comes out without having to match so many seams. I love the pattern but won't be able to try it any time soon.
