A ballpoint drawing of a red Ferrari, very challenging. I used a “Pilot” brand for this experiment. I checked with another brand “Uni” with a darker tone result but blots a lot. I will try again with “Bic”. I am using regular ballpoint pens.
Blot is a common enemy with ball pen and the tip is, have a cloth, tissue or cotton to scrub the excess if ink is building on the tip of the pen.
Keep practicing. Enjoy.
