Using my Twisbi Iris VAC700R to create different line weights and variation by adjusting my writing pressure and grip, and using different parts of the nib to sketch with. This is to see how much line variation I can get out of this fountain pen that I love using for urban sketching.

Using the first pen I bought when I started sketching – the Yellow Lamy Safari fountain pen – to experiment turning the F nib into a Fude nib.
