I have made all my stuff-sacks (unless gear came in one). After I made the hammocks, I had strips of fabric left over, and wanted some sacks... perfect combo!

I keep my hammock, straps & bugnet in a sack. This makes them easier to pack, unpack and setup. The last thing in is a strap, so I pull it out, tie it, walk backwards letting the hammock emerge, and tie up the other end when it appears. Then I'm ready to go! (Unless I'm putting up the tarp, which is rolled in my pack.)

My blanket/sleeping bag came with a stuff sack, so I use that.

Small items (paper, pencils, camera, batteries, etc.) go in a ziplock baggie. The baggie keeps them contained and dry at the same time. It's cheap and ultralight.

If I'm going for more than a weekend, a trashbag lines the pack. Easy, cheap and lightweight.
