Those are beautiful blocks. I'm in awe of hand piecers.
Like Joyce, I was thinking sashing each block with a print--maybe a small plaid using the green, salmon and white? Or a celery green and salmon stripe? I just think you have already have a good bit of white. You'll have to figure out how big you want the overall quilt, and work backwards from there. Just one yard of may or may not be enough, depending on how big it is after sashing.
