I have a silnylon poncho with a 3/4 inch hem...it doesn't have any identifying tags but I bought it new. I'm wondering about fishing a paracord through the hem at both ends and putting toggles on the cords to facilitate gathering the material then using carabiners and couple of whoopie slings to create a quick trail hammock. What are your thoughts? Does silnylon come in different specs so that one might lend itself to this application while others would not?
