I live in Phoenix, and was traveling to San Francisco with my family.
This is my third trip to SFO and this time I took my pens and scetchbook with me. We stayed on 24 floor with amazing downtown views, so 3 of my sketches I made from the hotel room. Definetely a nice city to explore and paint around.
I used a simple R2 rollerball pens from a dollar store on Fabriano 1264 sketch book A5.
