Although 11ft hammocks are the norm, I am too lazy to cut 4" of fabric off to make the hammock exactly 11 feet. So, I have twelve feet of fabric and each end gets folded over two inches twice, so 12'- (2x4")= 11' 4" hammock. I can't do anything with 4" of scrap and I'm not into wasting stuff. Husband doesn't care about weight(yet) either.
So easy-peasy, I folded each selvage (the finished borders on the long edges of the fabric) over twice, approximately .5" and .5".
I used no pins and stitched the entirety of both lengths with the Mara 70 thread. I did have to play with tension with the thread and the light fabric, during which having a scrap of fabric would have been nice. I ended up stitching in the selvage and had to actually pull the bobbin case out and adjust the tension there.  Once that was settled things moved quite quickly!
For the end channels, I folded over twice using a tape measure to stay fairly straight.
I did use pins here, but just a few. I added three rows of stitching as per the Ripstop by the Roll video.
And that's it!
I made Whoopie Slings from a video on youtube. He first one went really well with no hangups.
I couldn't find my loop turner, so I just used a piece of floral wire left over from a recent project. It was really too soft but I made it work. The first piece of wire I used was only 12 inches or so and on the second whoopie sling I slid the bury past the end of the wire and got hung up. A few fibers hung between the wires and caught, keeping me from finishing the bury. I had to cut the wire to free it and start over. Not a big deal. I definitely suggest using at least a 20 inch piece of wire to fish with.
I also made two 6 ft tree straps. I made 4" loops and overlapped the webbing by 4 times the width or an additional 4". I read multiple articles on stitch pattern for reinforcing the tree straps with no consensus whatsoever. Some people use boxes. Some use zigzags across the width, some use straight stitches down the length. So, I did my own thing. I did three rows in each direction. I will watch the wear and adjust as necessary. They feel strong and I trust them as they are.
So my first try hang didn't work out. I ran the fixed loop of the Whoopie Slings through the channel of the hammock and used a Marlin Spike hitch to attach them to the tree straps. No luck. With the slings pulled all the way up, the hammock was on the ground. So I moved to another place in the yard and the trees were too big for the 6 ft tree straps. I need at least two more feet. So I took the Atlas straps from the kids hammocks and just looped the Whoopie's through one of the loops there. Whew. Finally hanging.
My whoopies won't work because I left too much space between the buries. It's 12 inches of dead space that can't adjust. At 16.5 feet between the trees the hammock was almost on the ground. So we cannibalized one of the slings for two continuous loops to run through the channel. Â
So much better, Marlin spike hitch to the continuous loops got hubs hanging at a respectable height without climbing the tree to run the straps!
So I will keep both 6' straps but will make one strap from the rest of the 25' of webbing. 6 feet will fit in some places and can also be used as extenders. I am also keeping one whoopie sling but I can't see every needing to hang that wide to keep both. I am also considering making UCRs with the other piece of amsteel. Ikept the fixed loop portion from the whoopie sling I made the continuous loops from, and will make a dogbone to use as an extender as well.
