I love the honesty. Aren't you glad that she told you before it was done and you'll be able to make her something that she really likes?
My DD is the same way but then that's how I raised her to be. I've always said, "You can be truthful without being mean. If you don't like something just say, "That's not something that I'd go for but if you like it that's great, we not supposed to like the same things.""
