Hello again gang. Im trying to decide. I don't have the money to buy a good tarp before next weekend. So I'm thinking that I'm going to use a regular old poly tarp. But I can not seem to get the sizing right. How much over hang should I have on the ends of my hammock (120" whipping to whipping ). I was thinking something 12x12 would give me a little wiggle room on the ends and allow me to tuck the ends to form doors if the weather gets ugly. However, a 12x12 tarp seems to be a mythical beast. 11'6" x15' seems to be the closest compromise with out having to perform major surgery on the tarp (which I'm not adversed to I'm just weary of doing it to the device that will serve to keep me dry )

So what are your thoughts?
