Thank you BillyBob, that's very clear, both words and pictures.
It looks like you don't tie the peapod above the knots on both sides? I made a vow yesterday night to always make it at least that tight, as I said I had 10 cm between the occupied hammock and the pod (and it was cold). Of course it differs for everyone.
I'm thinking about that mosquito hammock BillyBob suggested, that gives a warmer fit with the PeaPod, right? Although I'm not going to try it just yet.
