Open Microsoft Word, or another word-processing program, and click File/New. Search the New Document/Template list for banners, and select a banner from the projects list that is suitable for your occasion.
Select the text in the banner, and type in your own greeting or title. Adjust your font style, size and color in the font settings.
Customize the decorative graphics in the template by clicking on them, then click on Insert/Clip art, and search for new graphics such as "border" or "party." If necessary, re-size and adjust the graphics' placement on the banner so your text is not blocked from view.
Save and print your banner.
Assemble your banner using tape to attach pages to each other in proper order. Trim edges if necessary. Use tape to attach your banner to a wall or other surface.
