I need some help rigging a poncho tarp in the half-pyramid setup. I want the whole tarp to be raised up off the ground a few inches. To that effect, I have added 8-inch aircore guylines to the 4 corners and the rear center. However, when I pitch it, I find that the edges of the tarp are right on the ground, with the guylines running along the ground to the stake.
I suspect it has something to do with how much slack I need to allow in the guylines on the back side before I raise the front with a trekking pole. Or maybe with the length of the pole, or the length of the guylines. I need the extra interior room for my 6-2 height, otherwise my long sleeping bag touches the tarp at both ends.
Anybody have an idea? Thanks.
