This quilt will be beautiful. I love it. I am very fond of Frank Lloyd Wright architecture, but I had no idea that there were quilts that had been inspired by his beautiful windows. Just wow! I had a great time reading about Frank Lloyd Wright quilts, and if the price of the book wasn't so high, I might consider trying to make one...emphasis on the "trying."
Your quilt is just wonderful. I am sorry that you currently hate it, but I understand that feeling well.
That feeling will pass and you will have a great quilt.
