10 x 20 cm Canson 125 gr/m2
For small parts in black and color, I used the felt Stabilo POINT 88 fine tip, line width 0.4mm.
What is sometimes interesting and sometimes unpleasant is that the felt is soluble.
For the part in yellow, it’s liquid watercolor Pebeo.
Finally for the big part on the right, I did a wash with water and graphite Artgraf Viarco .
