I use a catapult with a heavy hex nut to launch a thin cord over suitable branches and then draw the heavier rope over and across the space between the trees. The cords across the air vent in
the centre of the canopy can then be attached to this line with a strong karabiner and hoisted up.
To spread the material over your working space you can just tie it directly to suitable trees or bushes but a better way is to make a perimeter line around the outside with another strong line and then attach the edges of the chute to this with lighter cord or even “bungees”.
In use you will find that the outer edge drips through as rainwater soaks though and anything
attached to the inside of the chute will make a drip point too but as these are in a fixed position they are easily avoided.
Certainly if I am running workshops or even just enjoying company round the fire in the evening, I find such a parachute shelter very useful on a static camp.
