It is a wonderful quilt. Since it is your daughter, and I'm guessing you can speak openly with her, why not ask her to explain how she feels about it. I can be she appreciates your effort but something about it doesn't resonate with her. It could be the color combination, or the pattern or maybe she doesn't like the look of lots of triangles. And the discussion can lead to a better understanding. Maybe you can make her a different one that is more appealing to her.
