Looks can be deceiving if you have the right phone case. Today’s DIY video does just that with a paper notebook hack that literally cuts things up just the right way. If you have some glue, an Exacto knife, and some DIY spirit, you too can look like you’re playing in your notebook. Or, be a good student, and use it to take notes while recording the lecture for test time studying.

It’s not 100% foolproof as the person next to you will definitely see your phone sitting in your notebook, but in a lecture hall of over 100, you might look studious with the right stylus.
