With rope.........

Seriously, I haven't hung any in a long time, but I like to use what I call Adel clamps. Basically the same thing you use for wiring harnesses and such. (just a larger version)
I'm sure there's another term for them.... I call them Adels from the aviation days.
Adels actually have a metal band in them, but you really only need the plain plastic ones.
I'm sure there's better suggestions out there as well.
