Working on Garden Quilt Top

I have been trying to finish up the applique on my pieced and appliqued garden quilt. i started this in Mary Lou Weidmans class in May and have been working on and off ever since. There are lots of cats and birds. It's very colorful and makes me happy to look at it. I have a few more bugs and butterflies to put down and the sun needs to sewn down. Just trying to figure out what I should do to the outside edge. I need a small border but I don't know what to put down. Hmmm. have to think about it.
