I started this new IGTV series, where I will answer some of the most common questions regarding watercolor and drawing basics.
In the first one, How do you do the outline? and which pen do you use?
The pen I usually use is PILOT (or MICRON would work, too) 01, 03, and 05 depending on the thickness I need. The most important thing is they need to be waterproof.
