GFG edge quilt motif design

My GFG is progressing nicely, I've just finished the quilting of the flowers themselves. But how to quilt the edge? I don't yet have an idea, but tonight I'm going to start sketching some possibilities.
This graph paper will come in handy. I printed it out  from Incompetech, and colored in the areas that are available to be quilted. Let's see what I finally decide.
The cross-hatched area is already quilted, and I've shown about half of each side. 
Your suggestions are very welcome.
