When writing a wedding card for a friend, its important to consider your relationship with the couple and how personal or formal you want your message to be. Here are some tips and examples to help you get started:

• Address the card to the couple as a pair, and congratulate them both.
• Plan in advance and write out what you want to say on another piece of paper to avoid errors.
• Write from the heart and be true to yourself and your relationship with the couple.
• Keep your message short and sweet, as wedding cards usually dont allow for a lot of space.

Examples of what to write in a wedding card for a friend:

• "Cheers to love, laughter, and happily ever after!"
• "To my best friend on your wedding day, know that your happiness is everything to me. The fact that youve found your someone means the world. Congratulations!"
• "Of all the special milestones weve celebrated together over the years, today tops them all."
• "Weve shared so many happy memories together and this is no exception."
• "You make the perfect couple and I couldnt be happier for you both."
• "You are reaching a huge milestone in your life as you marry your beautiful bride/groom. We are so proud of who you have become and feel so lucky to have you both in our lives."

Remember, the most important thing is that your message comes from the heart and reflects your relationship with the couple.
