Creating Your Own Design Template
Sometimes none of the existing design templates offers exactly what you're looking for. In that case, you can either modify an existing template or create one of your own. The following are some ideas of things you might want to do to customize or add to a blank slide:
Change the master title or text style to a different font (View, Master, Slide Master).
Change the background color (Format, Background).
Change the slide color scheme (choose Color Schemes from the Slide Design task pane).
Change the bullet styles (Format, Bullets and Numbering).
Add objects such as a logo, picture, or WordArt image.
To save a customized design template for future use, follow these steps:
Choose File, Save As to open the Save As dialog box.
In the Save As Type drop-down list, choose Design Template. The Save In drop-down list selects the folder in which you store design templates by default.
Enter a name for your design template in the File Name field.
Click the Save button.
The saved design template is available the next time you open the Slide Design task pane.
Note
To delete a design template you no longer want or created by mistake, select the template in the Open dialog box and press the Delete key.
