In the video, a person is using a ruler and a pencil to draw lines on a piece of paper. The person is drawing a series of parallel lines, creating a pattern on the paper. The ruler is used to ensure that the lines are straight and evenly spaced. The person's hand is steady as they draw each line, and the pencil leaves a clear, dark mark on the paper. The video is shot from a top-down perspective, allowing the viewer to see the entire process of drawing the lines.
