Laura, that's gorgeous! What a cheerful, happy quilt! And I love your idea of stringing a wire to hold up all the finished tops. I've got mine draped over the upstairs balcony, but with one on top of the other, I don't have as good a view as you do. Good thinking!
I'm also addicted to feathers - I like other designs, but once I caught on to feathers, I tend to put them everywhere.
