Take it out of your car kit and bring it into the house because you’re sleeping with it tonight. It will reflect your body heat back at you, helping to keep you warm. Ideally you’re going to want you in the bed, a regular size flat sheet over you, then your regular blanket with the mylar blanket on top of that attached somehow–I recommend medical tape, because that’s what I use due to I already having it around, but any old tape should work.
