There is more than meets the eye to this card.
I cut a slit on both sides of the focal image (by Hero Arts)
then stamped on a piece of paper (images by savvy stamps) the width of my slits.
I inserted this paper behind the image so it can
be pulled either way to view the message.
It is really cool how this works IRL.
**I followed the outline of my focal image for the
slits so they would be almost invisible**
