A large knife or small hatchet will turn branches with leaves into a lean-to with either bark ties or paracord. However, if you have a few feet of paracord and a tarp, you simply tie paracord between two trees, drape tarp over paracord and stake one or both sides down, a'la Boy Scout pup tent. If a floor is needed, pine needles or leaves and branches can be fashioned into a floor. How much work to put into it is dependent on how long it'll be standing for your use.
