what she likes more: getting gifts; hearing you say something nice to her; you doing something for her; time you spend with her; when you hug her?
obviously she will appreciate all of those. but some more so than others. this is, of course, in addition to the gift you have planned already
as for the gift itself... well, generalizations is best we can do unless you tell more about what she likes or don't like, etc. generally, it's the thought that counts though, so don't sweat it too much. and hand made is generally better than store bought.
