How about a special journal or notebook? You could find a blank notebook and decorate the cover with her favorite bookbinding techniques, or you could look for a pre-made journal with unique binding such as a coptic binding or Japanese stab binding. Another idea is to find a bookbinding kit that she could use to create her own journals or notebooks. Additionally, you could explore the possibility of attending a bookbinding workshop or class together as a special Mother's Day activity.
Or you can get her a star map with an important date you share.
