Put the filling into the center, turn one side to the center, continue to turn up once, leaving a throw around the edges, compact both sides to snap up inward, and dab the two corners down (you can smear a bit of water on them).

Place the filling in the center, fold it up diagonally, press the sides together to snap it up, and dip the corners down (with a little water).

Place the filling in the center, fold diagonally, turn one corner over to the opposite side, and turn the other corner over and dip (with a little water).
