Someone please tell me what Im missing here. I bought 3 tents with broken poles and ripped bugnets at a yard sale last year for $7.00. I opened one up the other day to source some netting for a DIY project and out pops this massive rainfly, so I go to the backyard and hang it up to find it about the perfect size but it sags in the middle a bit. Now here is my question, what are the cons of using this as a hammock tarp? It keeps a tent dry, already has tieouts sewn in , I like the color, I can hem that extra bit of fabric out of the middle to make it taught. Someone please tell me this will work or they have done it. Thanks - Bob
