I don't think I've ever experienced such an intensively creative 3 days! The 2011 Urban Sketchers International Symposium in Lisbon was dawn til dusk sketching, talking about sketching, learning new ways of sketching, sharing sketchbooks and chatting with sketchers from literally all over the world!. We did two 3 hour workshops each day, drawing and painting on location throughout the city, plus lectures in between (we even sketched while we listened). During our evening meals, most people still kept drawing. I came back exhausted but buzzing!
