I think your scrappy quilt is good to go too! I don't think it needs the hunter's stars at the corners. Not sure if your thought was to reign in the rest of the quilt with them and a solid border? Don't think that would have the desired effect though. A solid frame would take away from your current quilt. A pattern frame would take away from your current quilt. Save those wonderful hunter's stars for their own quilt!
Congratulations on retiring! Time to sew/quilt/enjoy life!
