Beautiful quilt. I like what you are playing with in EQ6 for border treatment. I also like Dunster's border. Another thought is a 3-d look border like I did in Kitties dancing with the stars. It is very easy and you can incorporate your dark and light blues and greens if you have more of those fabrics. The top part of the border closest to the quilt can be the beiges, kind of like what I did with mine.
