It depends on how you want to quilt it. When the blocks are sewn together now, you will have some nice big sections to do some fancy quilting in. Those white sections would look great with some secondary patterns quilted in as in Angela Walters quilts.
If you don’t want to do fancy quilting, then maybe some sashing would work. You could join them as is and then appliqué hexagons as sashing to cover the seams.
