Receiving a wedding invitation card is often a time for joyous preparations. After all, you want to celebrate the day with the happy couple. Whether you attend the wedding or have a prior commitment, you should share you enthusiasm for the special day with words of congratulations. However, not everyone is a natural wordsmith. A thesaurus can help you find the right words instead of repeating the same ones over and over again. Writing out a rough draft or two can help before you transfer your message into a card.
