How do you trace a line?

To trace a line, start by placing a piece of transparent paper or a clear plastic sheet over the line you want to trace. Use a pencil or pen to carefully follow the contours of the line, applying consistent pressure to create an accurate copy. For digital tracing, you can use graphic design software with a pen tool to outline the line on a digital layer. Finally, remove the overlay or hide the original layer to reveal your traced line.
