Hello! I have a penpal in Finland who will be getting married in a little over a week. I was invited to her wedding but unfortunately cannot make it. I would like to send her a gift along with a card, and to make it extra special, I would like to write a message in Finnish to the happy new couple. Is there a direct equivalent of "Congratulations on your wedding" or some phrase that is commonly used in Finnish to congratulate them on their marriage and wish them a long, happy marriage together? Thank you in advance. I greatly appreciate it.
