I wanted a bishop bag for my tablecloth hammock. I thought about sewing one but then remembered my thread injector skills are less than stellar . This is where my "secret spaceweasel" comes in. In my box of goodies was a therm a rest stuff sack. Why couldn't I use that? Well I test fit the hammock( I really didn't think it would all fit) and it fit with room to spare. I put in a grommet just above the finger pocket handle . The little pocket keeps my whoopie sling nice and neat.
