The video shows a person's hands holding a piece of paper with a pattern drawn on it. The person is pointing to different parts of the pattern and then places a ruler on top of the paper. The person then uses the ruler to draw lines on the paper, presumably to create a design or pattern. The video is shot from a top-down perspective, and the person's hands are the only part of them visible. The pattern on the paper appears to be geometric in nature, with straight lines and angles. The ruler used is a standard metal ruler with measurements marked on it. The person's hands are steady, and they seem to be experienced in using the ruler to draw straight lines.
