Draft idea for a card that could be mailed to visitors. This is the inside of the card.
Note that the layout is for pre-scored greeting card, so you need to visualize this as folded horizontally across the middle.

The text here is only for demonstration. A more specific greeting message can be placed anywhere on the card - the idea is for the large logo to fade into the background so text can be placed on top.

This is an alternate version, where the church image is screened so more text could be placed over the imate.
