Every year the Urban Sketchers organisation, to which I belong, has a symposium. It is held in a different country each time and, in 2013, it took place in Barcelona - a very sketchable city! At the symposium there are workshops, lectures, demonstrations, sketchcrawls and lots of opportunities to draw out in the streets with fellow enthusiasts. Sketchers come from all over the world to learn from each other and celebrate location-sketching. These are my sketches from the event.
