I like Kassaundra's idea but would want to have the star cornerstones really stand out, so would probably only SID with them and then do a tight chevron on the blue sashings. Individual motifs on the blocks---I would do continous curves on the red & Blues to form a curved X and then either do a straight line (long ways) though the tan or more if wanting denser quilting, or a chevron in the tan to continue the chevron idea from the blue in the sashings.
