I was digging thru my goodies today, and discovered something I forgot I even had...a standard OD pesonnel parachute canopy (minus the lines, so I can't use it go jump off of the roof or something). Then I looked at my USAF survival manual and saw all the neat stuff you can make with a few (usually six) gores from the 'chute. Before I cut this thing up, has anyone actually used parachute parts for shelter, sleeping bags, hammocks, etc? Is it worth the trouble? How big would six gores be, rolled or stuffed as small as possible???
