Adding a simple pocket to the inside of the front cover of your pocket notebook is an excellent way to expand the notebook's organizational capacity.
I use a small template in order to make quick work of creating a new pocket.
Below is the template and visual for using the template.
PLEASE feel free to save the template and print at your leisure. Print at full screen.
I prefer to use old photographs, postcards or some kind of thicker card stock that I can draw on. My overall preference though is for photographs. They really do hold up really well (unless you have a really sweaty bum) and add a meaningful decorative element to a strictly functional pocket.
With the pocket added, I can now easily include my trusty grid ruler and some index cards.
Life becomes a bit more complete now.
A parting shot of the changeout from one "pocketed" notebook to another.
