Step 3: Tape plastic to windows.
Clean the window framing to remove any dust, dead bugs, etc, so that the tape can adhere to the surface. Tape plastic starting with top edge to the framing, Continue in a circle, until you are finished. I would not recommend taping top-bottom and then sides as this seemed to leave a less taught plastic, and I could actually hear it rustle when a wind blew -- confirming that I had a substantial leak. Gotchas:If you care about the wooden framing around your windows, do not attempt this as the duct tape will leave marks on it, or worse.
