I've been meaning to pick up some triangle thingies, but just haven't gotten to it yet. I toss around a lot in my sleep, and sometimes this shifts my 3/4 UQ to one side of the hammock. The triangle things would help pull the lines up and keep it in place better.
So on my last trip, as I flopped from my back to my side and my UQ shifted, I began to think what I could improvise right there. I pulled out an S-biner and hooked it to the lines as shown below and it worked perfectly! This really allowed me to open the end channels up to give better coverage under my hammock, but keep it snugged up to me as well.
Just thought I'd share.
