If you could only take one pen out urban sketching, could you do it? If so, what pen would you use? I considered but discounted my fude collection in favour of the Twisbi Vac700R, and am wondering if she can give me all the line variation I’m looking for. Is she “the one”?

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.

A step by step approach to adding tonal shading, adjusting saturation, and emphasising lines to add depth to a Toulouse street scene sketch, and create a strong focal point.
