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 cousins that love a good laugh, then 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 by personalizing it to your cousin's personality will make it special—even if it's just a couple sentences.

The most important thing to remember when you put pen to paper: Write from the heart. If it helps, you can even scrawl down some drafts before choosing your final message. Still in need of some inspiration? Check below for some examples on how else to say "best wishes" for your cousin's wedding.
