The spinnaker stuff sack pictured is the last one I made. It is 16 by 8 inches, weighing in at a respectable 11 grams, or 0.39 ounces. It's not a perfect piece as I'm still stuggling a bit to sew straight on the slippery spinnaker, but quite servicable - just don't expect MLD quality and a warranty to boot :). I followed the instructions at thru-hiker.com, deviating slightly by not making a 1/4 inch hem before folding over and making the channel. Frankly I didn't see the point in stiching that. I also made the channel wider to make it easier to use the drawstring for opening and closing. The first one I made had a narrower channel which when tightening the drawstring would provide to much friction.
Here are some pictures from the construction.
Take care!
