In this video, Ngai Chun Cheung demonstrates how to make an origami suit jacket. He begins by folding a right triangle and tearing off the excess to make a perfect square. He folds it on both diagonals, then folds the four corners into the center. He turns the paper over and folds all four corners into the center again. Then he turns it over and again folds all four corners into the center. He turns it over and opens the four corners partially and folds them flat to make rectangles on all four corners. Then he turns it over and folds it in half downward, making a suit jacket shape. He opens the middle and folds tiny lapels onto the suit jacket, then folds the exposed layer downward to make the shirt collar. This video is very easy to follow and shows how to make a very realistic suit jacket out of a square of paper.
