My homemade mosquito net tent works well with my 8x10 tarp. It does not work with my poncho. The poncho has velcro on it so I don't even want to get near my gossamer cocoon with it. But even without the velcro, it's just not the right size or shape to work with the poncho.
Because of the way I made the edges around the bottom, I can use stones instead of stakes, which is nice. That means I don't have to carry extra stakes if I need to use the tarp to form a roof. Since the tarp can only be set up one way using the net, there is no room for creativity and I can leave extra guy lines home, too.
The weight for the tarp plus mosquito net compared to my tent is heavier. But I can sleep without a roof now without worrying about mosquitoes. So for a few extra ounces I think it might be worth it to sleep peacefully under the stars. Since it is summer, I can leave home other things when using the mosquito net so it will all even out.
Now I need to make an esbit stove.
