Overcoming personal boundaries and fear can be one reason to keep up with a sketchbook but it can also be used to stimulate creativity for specific projects.
The aim is to become bold in formulating gesture with a pen, marker or even a brush, to trust own abilities in visualisations skills. More than ever the hand and the brain have to be trained in acting in an analogue creative way without the limitation of computer software.
Sketching often includes collages, lettering and creative writing.
I offer talks and workshops to use a sketchbook as a design tool.
