Your prefered method and knots for tensioning a tent or tarp?

Just curious what everyone uses for tensioning a tent line or tarp? What hitch do you use for attaching the line to the tarp eyelet? Do you use a trucker hitch or just a simple friction hitch like the adjustable grip hitch to tension the lines?

I’m looking for the best method to accomplish this using paracord or other 3mm cords, without causing too much cord damage and also being able to untie everything esily.
