The humble pencil. During my time in Umbria, I saw what Amity Parks could do with a pencil, so when she landed in nearby Guelph, I just had to take her popular Sharp Pencil and Keen Eye workshop.
In class, we played with many (many!) techniques, but I was particularly drawn to playing with pressure and release on Roman capitals.

Same technique on Arches hot press (smooth) watercolour paper.
Experimenting on paper with a bit more texture.
