I will show two ways to always carry duct tape in your pocket. The first method is circular in your pocket and the second is flat, sorta like a credit card.
P.S. This is my first Instructable so please spend a minute to give me feedback. Thanks :-)
Step 1: Materials
If you are going to do Variation #1, then you need a BIC pen.
If you are going to do Variation #2, then you need a card. Like an old credit or library or some membership card. You could also use those credit cards that you get in the mail that you don't activate.
