Pocketmod is a neat site that lets you pick and choose ‘pages’ for a printable page you can cut and fold to make a tiny folio or organizer.
You can pick reference pages such as tips table or conversions, or task lists and calendars. You can even pick a custom page to add what you like.
Its free. Uses a single 8 x 11 sheet you print out. Make a single cut, and folder to make a tiny booklet.
