Trace the Oval

What happens here

With the string loop now around the two remaining nails, insert the notched pencil into the loop. Hold the pencil upright and pull it taut against the string, ensuring the string remains tight around the two nails and the pencil. Starting from one of the previously marked points (e.g., the bottom point of the vertical axis), guide the pencil while keeping the string taut. Move the pencil around the nails, allowing the string to dictate the curve. Draw one half of the oval, then repeat the process for the other half, meeting at the starting and ending points to complete a continuous, perfect oval.

Goal: Draw the complete oval shape.
