Rectangular paper box: this is a simple and practical origami making, which can be used to store small items and also to hold gifts. You need to prepare a rectangular piece of paper, such as A4 paper or envelope paper. First, you should double the paper diagonally, and then open it. Next, you have to fold the four corners in half to form a square. Then, you have to fold the two sides of the square in the middle and open it. Next, you have to fold the top and bottom of the square in the middle, and then open it. So you get a grid with 16 small squares. After that, you have to turn the four corners of the grid outward along the diagonal to form four triangles. Then, you should turn the left and right sides of the grid inward along the center line to form two rectangles. Next, you should turn the top and bottom of the rectangle inward along the center line to form a small square. In this way, you have completed the bottom of a box. Finally, repeat the above steps, but leave a little space in the last step and don't fold it completely. In this way, you have finished the lid of a box. You can put the lid on the bottom and get a complete rectangular carton.
