This video tutorial is in the Arts & Crafts category which will show you how to make a box out of scrap paper. Take a piece of square paper and fold it across both the diagonals to get an intersecting crease. Now fold all the points to the middle of the sheet and unfold them. Now take any point and fold it to the furthest away intersection point. Repeat with the other three sides. Then fold all the four points to the closest intersection point. Now you will see a square in the middle of the sheet. This will be the base of the box. Now cut the sheet as shown in the video to make flaps and fold the sides upward to make walls of the box. Watch the video for the full demonstration.
