These are the handouts.
I first did some warming up exercises.
Then I had the group experiment in making different types of lines.
My point was, that most sketchers are too busy staring at the subject, that they forget the means that they use.
Good line work, as with good colourwork, will enhance what you are trying to tell.
I had barely time to prepare for the meeting, I sat at a restaurant in a hotel in Rotterdam, and figured out that I had to make some examples.
So I took the subject in front of me: an ugly little Christmas decoration on the table.
I did different techniques:
1: Open linework, cross or break lines.
2: Colour and line independent.
3: Watertight ink: thick/thin lines
4: Non-waterproof ink: allow the water to bleed the ink.
5: Chinese ink and bamboo pen: the line textured: from black to grey.
