The Zero Degrees micro brewery we painted in 2009 has just undergone a major refurbishment and we were invited back to rework and refresh the large 13m mural. The aluminium wall was plastered and created a great blank canvas, just like a new page of the sketchbook! The brief was to create a diagram of the brewing process and working with the sketchbook vibe we created a free flowing annotated line drawing. The finished mural looked great, as did the refurb.
