I just use a simple slip-knot daisy-chain (also know as a sea-chain), although I've seen other ways as well. But the sea chain is super fast, easy to learn, and unties even faster. The sea-chain creates a paddle rack that is just under a third the length of your rope. So 15 meters of rope will give you between 4 and 5 meters of paddle rack; enough for the standard tent, and enough for one team. You can use cheap utility cord, but my favourite was 15 meters of buoyant heaving line from an inexpensive kayak rescue throwbag bought at MEC. Add a couple of large carabiners to the throwbag and the rack is super quick and easy to hang.
A Google search resulted in this overly long video of the sea-chain technique.
