Jim, I made my first hammock, which I still use today and find very comfortable and lightweight, from stock width, 12' of ripstop. I hemmed the edges with 1/2" hems and sewed 2" rope tunnels at each end "asymmetrically", meaning when you thread in the suspension ropes, the sides are pulled 1" tighter than the middle. The material was right off the bolt at Walmart...96" stock width, I think.
This is my loaner hammock, and a simple cot bug net drapes over the top with a ridge-line. Poncho shelter is the rain fly.
It's plenty wide to lay diagonally, or center-line. I don't bother guying hammocks so there is nothing else to do with this design....very simple and functional.
