I recently attended a one-day techniques workshop given by an amazing and talented teacher, Pat Bourque. Her many years of teaching experience really show up in her workshops. I would highly recommend her workshops to anyone!
We did this study on a stormy sky. The sky is painted with a brush but the foreground is all painting knife work. I was very happy with the results of my painting.
The afternoon was spent on value, florals using more palette knife techniques, medium additives, etc. Awesome Workshop!
