Download and print the Pet-Adoption Announcement template; cut out.
Print your new pet's name and other information on cardstock. (You may be able to make two cards from one sheet of cardstock, depending on the template you'll use.)
Hold the cardstock, type-side facing you, against a window and place the template over it; the light shining through the paper should help you position the template properly, so the message is straight and centered.
Trace the template onto the cardstock; cut out. Erase pencil marks, as needed. Place a ruler across the animal's back (where the card's fold will be), and run a bone folder alongside it to score the cardstock; fold to create card.
