Hello all!
Newbee warning!

I was wondering if anyone could help me with a fabric question?
My diy hammock turned out to be a bit to heavy for my liking. It's made from nylon or polyester fabric I found in a local shop.
Because of my newbe-ness I decided to make it double layered.
Specs:
122 x 52 inches, 42,32 unse without suspension.

Can anybody tell me what the fabric weight will be (oz/sq yard) ?

Hammock used 6-7 times, does not seem to have streched, I can't strech it by hand neither, is it most likely polyester?

My weight is 245 pounds, would it be "safe" for me to remake it into a single layer?


Thanks

Torstein
