What gift should you give your mother for her second wedding?

well, when my mom started dating her now-second husband, i openly resented the guy. but i got over it right about when they got engaged. so i gave my mom a really nice photo of me and her and the new guy on a roadtrip we went on. i gave it to her i think two days before the wedding, and it meant alot to her. it showed that i accepted him and stuff. but if that's not how it is for you, i recommend something personal, something that shows how you and her have changed/grown because of your new lives. this sounds so corny but shes a mom about to get married, she loves corny.
