There are three pages in this booklet: the tracker in the preview above, a month-on-one-page calendar, and a before-and-after summary page.
The border is large enough for punching along one side, or you can tape it into your planner and trim the excess instead.
You can either print all three pages (which gives you a blank side for extra notes) or print just any two pages you need double-sided. You can even fold it in half and trim one side so it opens out and doesn’t cover your weekly spread altogether if you want it where you can’t forget it.
Print on A4 (make sure to uncheck “fit to size”) and trim the excess.
