This is a fun card that the couple can either have a printed message or write their own. They can have their names printed on the cards along the top or at the bottom. Popular choice is also to have a thank you message as well as "Please keep the 10th December 2005 free as we hope you will join us as we become Mr & Mrs".
Obvioulsy we have more formal text alternatives but whatever you decide tou have complete flexibility to choose the card and amend it to suit your needs.
