What is a one-sentence summary of the following article?
Working from the middle of each side rather than the corner, bring two sides that are next to each other up and over the center of the wrapper and the center of the filling. Press the middle of both sides together. Again working from the middle of each edge, bring the sides up and over the filling to the center point of the wrapper, where the other two sides have already been sealed. Press the center of each edge into this point, sealing all four sides together. You should be left with a shape that looks like an "X" with slightly open corners.

Summary:
Bring two adjacent sides together over the filling. Fold the remaining two sides to the same point.
