Forgot to add a positive lesson to my post 
I found that if I needed a small piece of duct tape, it wasn't so easy to tear off from the roll. So I came up with this idea...
I bought a second roll of duct tape, and cut around the roll at the center of the tape. This gives me two rolls of duct tape at half the width of normal size and more convenient for the smaller projects.
TIP: You do not have to cut all the way through the whole roll, just use one side at a time. Once you start, the tape will tear down the center because of the tape on the other side
