One of the most quick and easy to erect survival shelters is a tarp shelter. It offers little warmth, but it can be a great refuge from biting winds, cold rain, and hot sun. Most tarps have grommets, which are great for tying off lines. But what if your tarp (or similar material) doesn’t have grommets where you need them? Or the grommets have been torn out? Or you need a tarp shelter that can break down quickly? In those situations, use these three tarp tricks to build your shelter quickly, securely, and easily.
