What to Write in a Cousin's Wedding Card

When crafting the perfect congratulations message for your cousin's wedding card, it's all about tone. If they're more sentimental, you may want to lean into a sweet message with a callout to one of your favorite memories together or characteristics you admire about them. For the cousin who loves a good laugh, sharing an inside joke or adding in a goofy pun will ensure it brings a smile to their face. You don't have to write a novel for it to be an impactful message either—just tailoring your wedding greetings for your cousin to their personality will make it special, even if it's just a couple of sentences.

The most important thing to remember when you put pen to paper: Write from the heart. If it helps, you can even scribble down some drafts before choosing your final wedding message to your cousin.
