Find a new template for your design by searching all templates while you are in the software.
To choose a new template from within the app select the TEMPLATES option as shown below. Then scroll to browse all available templates, or search for something specific.
Templates only show for your current product type. For example, if you are working on a flyer, you will only see flyer templates. If you want to start a new product, go to File > New.
When you switch templates, content will NOT carry over to the new design. Your current design will be saved to your account if edits have been made.
