How to Draw With Nib and Ink

This short video may be helpful for the beginners in ink graphics technique: here you can see the typical process of drawing with a thin nib and liquid ink.
I draw a simple berries sketch with contour lines, hatches, and dots.
I have two containers on my table: one with ink (black), one with just a clean water. The second container is used when I have to clean and refresh my nib. By the way, it's not a "duty" to pour ink into a separate container - you can use the bottle in which ink was by default (in the moment of purchasing).
I dip the nib into ink up to its small opening, then draw, varying the pressure on the tool. When ink on my nib ends, I take another portion of ink.
In this video, you can also see how I dab my nib with a paper towel and dip it into water. If you draw with liquid ink, the nib should be cleaned from time to time, otherwise, ink will dry up on your tool and lines will be thick and inaccurate or there will be an obstacle for the ink to leave marks on paper.
