I'm in the process of getting shockcord to make the tensioners. Gonna teach a class to my scouts so they too can make them.
My stakes are tenny tiny looks like clotheshanger wire w/hook at top that I used with my tarp tent (very very light weight) plus a couple of y light weight stakes and some MSR ones. None of these can hold very well in the soil that's at my house (basicly beach sand with some grass trying to grow on it) Took me forever to find my stake after it went flying. I ended up having to do what I call a "sweep", walking in a criss cross pattern until I found it. So basicly point / hang tarp with hammock end into the wind. I can do that as long as the trees cooperate and grow in the spots I need them to!!! I'll try some of my larger heavy duty stakes at home too.
