How about a fruit preserving set? You could include a set of mason jars, preserving sugar, and some labels for the jars, along with a personalized recipe book with some of your grandma's favorite fruit preserving recipes. You could also consider adding some fun embellishments like ribbon or twine to the gift to make it more personalized. Additionally, you could also get her a book on fruit preserving or a subscription to a fruit preserving magazine to keep her inspired and motivated throughout the year.
Or you can get her a star map with an important date you share.
