It is going to be cute whatever you decide.
I agree. Just SITD around the the pinwheels (careful to stitch outside the folded edge) and stitch the sashing and cornerstones. You might want to stitch down the center of each border after SITD. She is going to absolutely adore this quilt because you made it with lots of love !!
