The Postcard Creator will help you identify all the typical parts of a postcard, and then generate your own postcard messages by typing information into templates. You fill in the address, details on the postcard’s artwork, and the postcard message. The finished postcard can then be previewed, edited, and printed. After printing your texts, you can illustrate the front of your postcards in a variety of ways, including drawing a picture, creating a collage of images, or printing and pasting clipart in place.
Have fun!
