Create birthday cards in Microsoft Word by selecting New from the File menu and selecting Cards under Templates. In the right pane, select the required card design and dimensions. If the selected template is not present on the computer, the program automatically downloads it from the Microsoft website.
The Microsoft Word Templates window includes quarter-fold and half-fold greeting cards. The half-fold templates create standard-size greeting cards. Delete or edit the pictures and text on the greeting card template to customize it. Printing the card on greeting card stock gives it a more professional look. Specialty card stock is available from Amazon.com and office supply stores such as Staples.
