Instructions for making your own double-sided stuff sack: http://theultimatehang.com/2012/12/make-your-own-double-sided-stuff-sack/
Double-sided stuff sacks and Bishop Bags are a great way to pack hammocks. With two openings, each side of the hammock can be accessed. Clip on side of the hammock to your suspension system (tree straps, etc.) with the both sides of the stuff sack closed. Next, open the drawcord of the unhooked side and "reveal" the hammock as you walk to the other suspension system and complete the set-up. The stuff sack remains connected to the hammock on one end, making it easy to draw up and re-pack. Leave the stuff-sack side hooked to the suspension and pack from the other side.
