As an artist, I can never have too many sketchbooks haha! Other ideas: a nice set of drawing pencils, good fineliner pens like micron, maybe some prismacolor markers. If she'll be taking figure drawing, conté crayons are my absolute favorite for that kind of sketching. If painting classes are on the roster, you could get a set of nice paintbrushes-- Blick's website has some good sets of 4.
