Putting pen to paper is one way of saying pen & ink drawing. For the past 25 years it has been a passion of mine. Many times over the years, whenever my hubby and I went on vacation, I made sure I packed black markers and a drawing pad.
When on vacation, if I saw an interesting scene, I would find a nice spot to sit and draw. Whenever I drew outdoors, somtimes I would attract a small crowd of people watching me. This sometimes made me nervous, but it did not deter me from my work.
I always used Sharpie ultra-fine black permanent markers and a watercolor drawing pad. I get my best results with these. Here is an example of one of my drawings that was not drawn on vacation, but drawn in my parents backyard.
