If you're like me, you love these handy little notebooks for the lab and field, but where do you put the pen? Frustrated with losing my pens in my backpack, in the field, anywhere, I searched and searched for a simple solution. Some involved duct tape (sloppy), others were luxuries (Quiver), and some suggested wrapping the ribbons around the pen. I wanted more, but simpler. A simple little papercraft hack was needed. so after a few moments of thinking, I came up with the papercraft below. Now you can be awesome too, and keep your pen handy. US Letter and A4 sizes. Enjoy!
