This little chart shows the different types of venation. Sufferers from varicose veins look away.
I adapted this from another chart. It plays about with colour, a bit of brush control and, in most of them, painting negative spaces.
At this stage I am really wondering if I will be able to paint as finely as I will need to for future assignments on the course. Practise and stronger glasses I think.
As always, I am attracted to the patterns here and can see many posibilitites for design and painting ideas.
