What do I give her?

My best friend is moving out of state this summer and I don’t know what to give her. My other friends are very very good artists, and I know at least one of them is giving her a painting that shows the two of them together. I feel like I have to give her something other than words but I don’t know what. I want what I give her to have sentimental value. I can’t go out and buy stuff either because my parents won’t let me spend very much money even if its my own money. I feel like it’ll look bad if everyone else is giving her all of these going-away presents and I give her nothing.
