You can insert decorative text by using Insert WordArt
on the Drawing
toolbar (toolbar: A bar with buttons and options that you use to carry out commands. To display a toolbar, press ALT and then SHIFT+F10.). You can create shadowed, skewed, rotated, and stretched text, as well as text that has been fitted to predefined shapes.

Because a special text effect is a drawing object (drawing object: Any graphic you draw or insert, which can be changed and enhanced. Drawing objects include AutoShapes, curves, lines, and WordArt.), you can also use other buttons on the Drawing toolbar to change the effect — for example, to fill a text effect with a picture.
