How about gifting your friend a collection of poetry books from their favorite poets? You can also arrange a surprise private poetry reading session for the couple. Hire a local poet or spoken word artist to perform at their wedding reception or organize a small gathering of friends and family for an intimate poetry reading session. This would make the gift more personal and special for your friend. Additionally, you can also consider gifting them a framed poem or custom poem book that contains their favorite love poems.
Or you can get her/him a star map with the date of the wedding.
