Thanks for response.
Nice idea. Pockets could be also used for storing balloons like that:
Some of them have 100 cm length and 10 cm diameter. There are also longer but with smaller diameter.
Now I'm thinking of very light hammock for my summer trip on south. Probably sewing 6 pockets will avoid taking additional pad.
I'm wondering if this fabrics will be good and strong enough:
I think it could be 37 g/m2 (1.1 oz)... You wrote that you wouldn't do that.
I'm 67 kg or 148 lbs.
