It was love at first sight with this adorable applique. Then I found the indigo corduroy and green buttons to match, and the whole thing came together as a more wintry version of the Ray of Sunshine Dress (Butterick 3772).
I'm hoping to find some time to sit down and finish it next week, so more pictures soon.
In the mean time, details: The applique is made by Wright. I got mine at Hancock fabrics, but you can find them lots of places online, too.
