I'm looking for a large piece of nylon, thick silicon impregnated nylon, or some other lightweight, tuff, water proof material that I could make a survival tarp out of. Does anybody know where I might be able to find one? While I'm here I have also been looking for some good references on natural camouflaging techniques and scent hiding. What is the best twine or string to buy for cordage? Also, since this is a knife forum I wanted to say I just got my Northstar and it has quickly become my favorite blade, my VTAC handles most of the chopping (these two will be paired together for a while until I can afford a Linger WSK). Thanks in advance for any help.
