We used the 4" diameter dryer ducting for the arms. After a quick test fit, a length was selected for each of us and I cut them down. First step is slicing through the foil with a knife. The duct is one continuous coil of wire so you will need some wire cutters for this step.

Next, I took the wire cutters and split about 6-7 of the coils to make the ducting open up in our arm pits. The exposed wire strands were double wrapped in duct tape to protect our skin. This didn't end up being enough for me and I was getting stabbed by my costume for a couple hours.
