Your wall hanging is bright and beautiful. I really like the bright bali's and it souunds like you might too now that you've tried them.
It's funny how something doesn't appeal to us and then something we see changes our minds. I've never been a fan of scrappy quilts, until I joined this board. Now I've seen quite a few here that are really pretty.
Great job on your wall hanging. The hearts not to cover a mistake, but a "design opportunity") gives it great dimension.
