I have something similar, but not as nice! Your is lovely. I would edge stitch around the applique,all the pieces. The. I would do a loopy cloud-type thing in the sky and a pokey, grass type thing for the grass. Leah Day has some great fills that look like clouds and grass. Wish I had a picture of the one I did. The quilting turned out nicely, though the applique on yours is wonderful!
