Anyone who attended Art in Action 2011 could not fail to be inspired by the wealth of creativity exhibited at the event. I was privileged to be in the Sculpture section representing the EBTS and duties involved attending lectures and demonstrations given by two of our professional members, Jake Hobson of Niwaki and James Crebbin-Bailey of Topiary Arts.
