This is a "gate fold" invitation. The size of this card can vary depending on the event. This particular invitation was for a christening.
When the ribbon is untied, the interior is displayed. I used the same patterned paper on the inside as I did on the outside. 
The client requested that I create a thank-you card that would allow them to send a picture of their child. I used the same color carstock and patterned paper for the base of the card, and sewed vellum on the front with the sentiment pre-printed.
