DIY Emergency Shelter

The advantage a tarp like this has over plain sheet of plastic is that the space blanket will reflect heat back down onto you. If you combine this with a wall made from logs or rocks on the other side of the fire from you, this greatly improves the heating ability of a campfire, and reduces the amount of fuel you need to stay warm.
