One idea is to get your friend a custom jigsaw puzzle! You can choose a photo that is meaningful to the both of you or a photo of their favorite place, and have it made into a jigsaw puzzle. Another idea is to get them a puzzle holder or puzzle board to make working on puzzles more comfortable. You could also get them a puzzle mat, which allows them to easily roll up and store puzzles that are in progress. Or you could get them a variety pack of jigsaw puzzles with different themes or difficulty levels so they can keep solving new puzzles!
Or you can get her/him a star map with an important date you share.
