See video how to wrap a potsticker.
Once dumplings are wrapped, you can either boil or pan-fry them. To boil, just add the potstickers into a pot until they float atop. To pan-fry, coat the pan with oil and flour, and let the bottom of the potstickers brown. Then, add a little bit of water, place a cover, and allow to them to steam until the skin becomes translucent.
TIP: cook one potsticker in advance to make sure the filling has enough flavor.
