Gifts for my in laws

Don't know if I'm posting this in the right forum but this seemed like the best place 😂I really want to give a gift to my parents in law on my wedding day, I've already sorted one for my mother in law but struggling to think of anything for my father in law. I want to give him something meaningful as he has supported me so much and also as the wedding will be a bit difficult for him as he will have to see his ex wife (my mil) again for the first time since the split so I don't want to upset him. I just want him to know that he's been a better dad to me in the years I've known him than my own father has been my entire life and I want him to know I love him. I was thinking maybe just a simple letter but I would like to give him a gift too. Any ideas??
