Summarize:

Brochures are meant to be read quickly and easily. For this reason, standard fonts and lettering styles are preferable to more elaborate ones. A common typeface like Arial, Sans Serif, or Times New Roman will work just fine, in most cases. If you're designing your brochure on the computer, it's best to stick to a font size somewhere in the 9-10.5 range for your main text, since the panels are smaller than ordinary documents. You can go slightly larger for things like headings and titles. When hand-making a brochure, always print your letters rather than writing them in cursive. Pictures are useful for breaking up big chunks of text on the panel and giving your reader something interesting to look at. They tend to work best when they accompany an important piece of information. Place your images on one side of the page near the margins and format your text around them to make the best use of the space you have. Add your own hand-drawn illustrations or download images from the Internet that are appropriate for your topic. Avoid adding more than about 2 pictures per page. Too many can quickly become distracting and result in a cluttered, amateurish look. Don't forget that you'll need to provide citations for the images you include as well to let your reader know where you found them. Making your title and headings a different color than your main text, for instance, can create contrast and signal to your reader that they're encountering something new. You could also include full-color pictures for more vibrant detail, or even print or draw on colored paper in a light shade that won't clash with your lettering. You can easily change your font color using the text editor tools in your editing program of choice. If you're creating your brochure by hand, grab some colored pencils or markers for when you want to add a little flair.
Choose simple, legible fonts to make your brochure easy on the eyes. Incorporate pictures and other graphic elements throughout. Use color to add style and emphasis.
