How to make Horizontal Cards
If you intend to use your cardstock* rectangular cards horizontally and wish for both sides of the card to be oriented in the same direction in print, you will need to rotate either the front or the back image by 180 degrees. Generally, the easiest way to do this is to rotate the deck back image (if using one).
Another way to imagine this is that the Y axis of the template is where the card will fold to have the images oriented correctly.
Note that your card images must be in portrait format (not landscape) when uploading.
*This does not apply for clear cards. Clear horizontal cards will need to have both images oriented in the same direction when uploaded to be printed with the same orientation in print. Note that any text on the back will need to be reflected. You can find more information at https://help.thegamecrafter.com/article/488-creating-clear-cards
