Thank you cards often get forgotten after a wedding, or sent out really late. Why not make things easier on yourself by sending out and electronic thank you card to your wedding guests, and to those who bought you a wedding gift. You can then follow on your design or theme from your wedding and get them sent out very quickly.
The wording will be laid out for you and you can send a generic thank you to all your guests in one sweep. If you've asked for money as a wedding present, you can even have your Thank You card primed and ready to send the day after your wedding.
