Not all of planners or journals have their own built-in pen loops, and not all of the time we are willing to bring along a separate pen case. While there are available adhesive pen loops out there, it’s either hard to find, expensive, or does not entirely work with our chosen pens. Here is a quick and easy substitute for pen loops: binder clips!
Binder clips are quite versatile, and come in different sizes and designs. What I do is to choose an appropriately sized binder clip that would match both my intended pen and the planner or journal that needs the pen loop. I would attach it somewhere in the upper third to halfway down the planner/journal, and not push it all the way in. I would then hook the pen’s clip into the exposed area of the binder clip, and there! Instant pen loop!
The disadvantage to using binder clips as pen loops is that this won’t work for pens without clips. In this case, a proper elastic pen loop would really be necessary.
The biggest advantage to binder clips as pen loop is the wide availability, and in addition it would be easy to swap out and change on a whim. Have you tried using binder clips to hold your pens?
