With my rigid-frame shade structure, I would say parachute cord is probably sufficient. If you are simply tying shade netting between two vehicles, use 3/8" rope.
Sorry for the lack of pics, but I know google images can help.
The first shade structure is a Coleman event '14. It has 4 lightweight steel poles going from each floor corner which then connect to the center. The canvas on it reminds me of parachute material, mabye a bit thicker. I was going to rebar the 4 feet in place then use parachute cord on the shade covering back down to the rebar as extra support. I think the covering is velcro'd to the poles.
The next shade structure will probably end up like a monkey hut with thick silver tarp over the skeleton. I have no idea about anchoring this one because I haven't built it yet. Some of the pics online are hard to judge as to how the unit is anchored down.
Bob, I know i need to learn a few knot typing techniques.
