I'm sorry you had such a let-down with your beautiful quilt. The colors are spectacular; that quilt would bring cheer to anyone! Perhaps your friend is overwhelmed right now and really does appreciate your gift. Perhaps she just doesn't "get" how much time and effort goes into a gift like this.
Before I give a quilt as a gift, I try to make sure the recipient is going to appreciate it. Many years ago I made a quilt for my mother in law and gave it to her for Christmas. I used her favorite color (pink) and put a lot of effort into the quilt. She opened her present, said "Oh, thanks" in a very disinterested voice, and I've never seen the quilt again. As far as I know, it's never been on her bed.
