How about getting your grandma a sketchbook for Mother's Day? If she already has a sketchbook, you could get her a set of drawing pencils or pens. Alternatively, you could enroll her in an online art class or buy her a book on drawing techniques. Another idea is to get a custom portrait of her done by a local artist, which she could use as a reference for her own art. If you don't have time to do that, you could also get a nice frame for a favorite drawing she's already created.
Or you can get her a star map with an important date you share.
