I was recently asked if I use a palette knife - I'm excited it looks like I do - but I confess, I don't.
I took a class on the subject with Rob Longley, who studied under Henry Hensche - although RL is wonderful at his technique, I could not get it down and everything I did w/the palette knife looked furry - no matter what the subject, the side of an orange for instance, furry - the wall of a building also furry. . . I would love to figure it out someday.
BUT that workshop was really interesting because Rob Longley is also a great story teller and I learned a lot about Henry Hensche and what the summer art community was like in Provincetown years ago.
