I'm never done the Big Stitch hand quilt method, but bet it would look good on this quilt. Or you could do a simple circle around each flower--maybe the middle. The key to doing it on you DSM is getting it layered flat and well basted--and take your time. the other option would be to take to long arm quilter and ask for a "flowy" pantograph--which would probably also be your least expensive option with a long arm quilter--and would not take away from your intricate piecing.
