What was your favourite engagement gift you received and why?

My BIL and soon-to-be SIL just got engaged and I’m wracking my brains trying to think of a gift! Cash is off the table, but I’d like to send them something to mark the occasion. What was the best ‘thing’ you received as a gift when you got engaged? via /r/weddingplanning https://ift.tt/3n7JJtx
