^ I wonder why people like them. Reminds me of highschool.
I'm of the same thought. I'm a grown up and don't really want a cutsie room with hearts and teddy bears.
So I guess it depends on what your fiance is like. If she is more girlie and likes the cutsie stuff, you can go for the teddy bear and charms and stuff.
Otherwise, I would suggest doing what the earlier posters said and get her something that relates to her hobbies, likes passions etc.
