Did ours on MS Word. Started with a cover page with photo of us and lil bit of love story background. HAHA
Then a bulleted list of what's on the file. Started from chats before flying in to see me, airline confirmation, his boarding pass, hotels/Airbnb and restaurant reservations. A photo or two for each date and short description and who else was in the photo of us if there's any. We included remittances, gifts we sent each other etc.
