Absolutely true. I started my hammock conversion about 15 years ago when I bought a cheap Walmart net hammock. Camped in it a few times but decided it was too cold and you had to sleep "bent". I then made a hammock from 12' of full width, uncoated, ripstop...threaded the ropes in hems I sewed in the ends, hemmed the edges, and found hammock heaven. It's wide, and allows me to lay diagonally. Total cost was $4 from the $ bin at Walmart. Hennessey is basically the same thing with some serious refinements (like bug netting).

So, literally, you can take 4 yards of ripstop, tie ropes on the ends with sheetbend knots, and have a spiffy hammock, no sewing at all. Hang it loosely with some 1/2" braid rope, put your foam pad in there, open your sleeping bag like a quilt, and go take a nap. You'll then know if hammocks are for you or not.

My wife and teenagers EXPECT to camp in hammocks and argue over who gets the good ones. Nobody wants to pitch tents anymore.
