This question gets asked almost everytime we meet with a bride. Traditionally, registry information is not printed on the wedding invitation or any of the inserts. What we suggest to brides is that they create a wedding website (many are free), and put your wedding website on your invitation insert.
Wedding websites are so handy. Your wedding website can have your full registry information. It also can list accommodation in the area, or you can use it to post directions to your wedding venue. Wedding websites can also have pictures, and space to tell your friends and family how you met and how he “popped the question”.
Traditionally registry information is not placed on your wedding invitation, but it is your wedding, and we will support whatever you would like to do.
