WordArt can be added to your documents, just like any other drawing object. Choose WordArt under Picture... from the Insert menu. Or, from the Draw toolbar, click on the Insert WordArt button . You will get a WordArt Gallery dialog box.
Choose the style you want. You will then get another dialog box where you can enter the text, and set the font size and style.
Since WordArt is considered as a drawing object, not text, you can resize it, move it and change its format. You can also change its shadowing and 3-D effects, right from the Draw toolbar. You can use the adjustment handle to change the curvature and style.
