What a great invention! Any planner, notebook or book can have a pocket!
The Planner Pad Insta-Pockets come in a few different sizes, and in front or back pocket versions. You just peel off the backing and stick the pocket into your book.
My new Time Traveler day per page planner didn't have a pocket in the back, so I trimmed an Insta-Pocket to fit and now I have a place to tuck papers! Yay!
(Disclaimer: I am not affiliated with Planner Pad in any way. I was just really psyched to be able to put a pocket in my book! I ordered this Insta-Pocket last year with the Planner Pad that I reviewed here.)
