Done! I used a grey polka dot for the border from It's a Hoot by Momo. The grey is Robert Kaufman Kona Cotton Ash and the white is from the Bella Solids collection. The fabrics in the middle are from Aneela Hoey's Sherbet Pips collection, of course. I decided I really enjoy machine quilting, and I might be brave enough to try a larger quilt next time.
