Just wanted to throw a few more potatoes in the pot.
I tie everything down with bungies that are just barely tight but lots of them.
Like other great minds my vertical poles started life as extensions for paint rollers.
Half inch steel conduit slides very nicely into 3/4 inch conduit.
With various lengths, some flattened ends, holes at the end of most of them, I can create almost any length I want.
This works well with different size tarps or across diagonal, etc.
The little loops of bungee with ball or hooks on them are great too.
With the conduit, and little bungees I can set up my tarp for shade or rain.
