One idea could be to create a custom t-shirt printing kit for her. You can include blank t-shirts, fabric paints, stencils, and other materials. Another option could be to buy her a t-shirt printing class or workshop where she can learn new techniques and expand her skills. You can also consider purchasing a t-shirt printing machine or a heat press if she wants to take her hobby to the next level. Lastly, if you want to go the sentimental route, you can have a t-shirt made for her that features a design or image that is meaningful to both of you.
Or you can get her a star map with an important date you share.
