You may want to add vertical text to the yearbook.
Here's how to Add Text to Pages.
Adding vertical text with letters reading sideways
1. Add a blank text box or drag and drop one of the text graphics onto your page. Type the text in the text box. Turn the text box sideways by using the rotation point located above the text box.
Adding vertical text with letters reading downwards
1. Add a blank text box to the page. Add the text hitting Enter after typing each letter to move it to the line below. You can also type in all the text and click between the letters to hit Enter and move the letter to the line below. You will need to do this for each letter.
Note: The text box may bleed off the page as you are adding letters, but once completed you can resize and move your text box back onto the page. In Text Options adjust the size of your text if needed. When the text box is correct, click on it to drag and drop it to any location on the page.
Use Snap to Grid to make it easier to get your text into a straight position.
