I have commenced rendering 'Eager to Learn'.
Again with the same pyrography nib used for laying in the outline, but this time using a relatively low heat, tone is slowly built up on the timber surface, over time, as many passes are made with the pyrography nib until the desired tone and colour are achieved. These tones are then repetitively layered one over the other to achieve increasingly darker tones.
There are no really deeply engraved lines using this technique. Short, 'gliding-across -the-surface' strokes, in a stipple like pattern, gradually polish and darken the timber surface to produce a dark velvet like finish without any furrowed texture which can reflect a little light from the peaks of each furrow wall and reduce the depth of the darkest tones .
