That is beautiful. I love cathedral windows, but it looks so difficult I have never even looked at a pattern. And don't tell me "it really isn't that hard," because then I'll have to add another quilt to the someday list!
Seriously, you are doing a fantastic job on this. I can't wait to see the finished product. Your colors are so cheerful. Will you be using unique fabrics in every window or will you have repeats?
