cork board craft?

hi! first time poster here — looking for ideas on a potential gift I would like to make for my best friend. I basically wanted to make a decorated cork board / collage for her birthday, but I am having trouble deciding what to actually put on the cork board.

She does not like taking photos very much, so I cannot add photos of us onto the board. I’m trying to think of other things I could add — maybe some sweet letters for her to read, photos of some favorite characters she likes, some interactive pieces such as adding a few things in envelopes?

Just curious if anyone had any ideas for what I could add to it. Thanks for reading!
