White space is the least-expensive way you can make your newsletters more attractive and easier to read. White space begins with generous margins. Always provide sufficient "breathing room" at the tops and bottoms of your pages.
Consider leaving some columns blank. If you are using a three-column layout, omit text from the first column and devote it to photos, pull-quotes and short topics. If you plan to include a lot of photographs in your newsletter, include a scholar's margin, a narrow column along the outside edge of each page. This builds white space into each page and provides space for a variety of different-sized photographs. Small photographs can fit entirely within the scholar's margin; other photographs can extend into it from the adjacent text columns.
