In the video, a person is seen holding a piece of paper with a patterned design on it. The person is using a ruler to draw a straight line across the paper. The line is drawn with a pen or marker, and the person's hand is visible as they hold the ruler and move the pen along the ruler to create the line. The pattern on the paper appears to be a geometric design, possibly a diamond or diamond-like shape. The person's hand is steady, and the line is drawn with precision. The video is shot in a well-lit room, and the focus is on the person's hand and the paper.
