What if you use a felt pen instead of pencil to draw the line across the bottom of the paper?

Using a felt pen instead of a pencil to draw the line across the bottom of the paper will create a bolder and more permanent mark. Unlike pencil, which can be erased, felt pen ink is typically more difficult to remove and may bleed through thinner paper. This choice can enhance visibility and impact but may limit flexibility in changing or correcting the line later on. Additionally, the texture and color of the pen may differ significantly from a pencil, affecting the overall aesthetic of the drawing.
