lol, not sure if our sewing machine is quite up to spec for that sort of stuff, but I am thinking of making up one with the circle base and lots of stitching. Thanks for the input all.
Crundle
Just like a sleeping bag stuff sack - thats what Spills has and its plenty strong enough. DON'T... suspend your bag from its drawstring. you want to pull it closed and "strangle" the bag below the opening by wrapping a few loops of the drawstring cord around it - suspend from there. That way you are relying on the strength of the cord and the material, not how well the stitching holds in just the few cm where your draw string emerges from the bag.
