How about gifting your grandma a personalized letterboxing kit? You can include a unique hand-carved stamp of her initials or a favorite symbol, ink pads, specialty paper for letterboxing, and a journal to record her adventures. Additionally, you can add a photograph album to help her record each time she goes letterboxing. This way, she can keep track of all of her finds and revisit them at any time. Finally, you could also consider buying a book that has other fun locations to go letterboxing. This way, she can explore even more and find new areas to find boxes.
Or you can get her a star map with the date when she was born.
