A1 Blue Sugar Paper, Black and White Paint with Card
The first time I used the method of card painting (see my Angkor Wat Painting, which was painted a year after this). The white shows the light tone, the paper’s colour shows the mid tone, while the black shows the dark tone.
I focused on the outlines with the marker, then used the brush to do the darker tones on the painting. It also created a watery effect since the water from the brush dripped down the paper, also creates a bleeding effect. (Which inspired me to exaggerate this technique in Let it Bleed.)
