if they have a size problem then you don't want to keep the eye seeing linear. I would put the 8 flower motifs in a circle - row 2 &5 has pinwheel, 2 flowers and a pinwheel Row 3 &4 has flower, 2 pinwheels and then another flower. rows 1 & 6 are just pinwheels. You could 'even' out blocks with different sashing widths. Put your best 4 pinwheels in the center. No one but you will know there had been a problem. I love your applique work!
