I looked at the iron-on threads... interesting. then I did searches for examples but didn't find any. I did find iron-on embroidered applique. some possibilities in tiny 1 1/2" pieces and if I could find a light blue flower that might do. Then I thought of the little flowers that are in the fabric I used. Maybe I could applique them all around the border. Or, I have a lot of the border fabric because I was going to use it for a border around the outside. Maybe I could extend that motif around the outside of it. Even leave it loose like prairie points past the point of the shadow.
