Sometimes you just don’t know where to start on a new project. Particularly newsletters or magazine layouts. Inspiration is everywhere, but often times having a pre-made template is a great way to start your layouts.
BestInDesignTemplates has several Adobe InDesign templates you can download and use for free, including: flyers, newsletters, catalogs, and a 20-page magazine layout. Obviously you would want to use these as a starting-point, rather than a finished design.
