You can make a greeting card with most any desktop publishing software but there are specialty products as well. These greeting card software programs feature ready-made templates, design wizards, clip art, fonts, or other extras to make it easy to design and print your own cards, announcements, or invitations. Most do many other print projects as well such as labels or fliers.
