If she likes it, that's all that matters.
I'm with her. For the life of me I don't see the allure in fat quarters, jelly rolls, charm packs, etc etc. There's always something in collections that I hate, and what a waste of money they are. Unless you're totally adverse to cutting fabric, buy by the half yard (or more or less) and stop piddling around with stuff someone else decided looked good together.
Just my humble opinion, of course.
