A: You can create a custom theme by clicking the Themes tab. On the following page, click Create a Theme, then select the starting template that you would like to begin editing. Along the left hand side of the page that follows, you'll see several tabs. Each tab controls a different section of the flyer. Using the tabs and controls, you can adjust the various design elements of each section of the flyer. You can also see what your theme will look like in both premium and standard layout as well as in Craigslist. Once you are finished, click the Save button. Note: The same sample flyer content is always displayed in the Theme Editor.
