Organized (very well) by Ruud Otten, Wiltfried Pathuis en Richard Veenema.
At least 60 sketchers were present that day, and even though there were a few drops of rain, it was a huge success.
I organized the only workshop that day: perspective drawing at Urban sketching. We assembled at the Mariaplaats in the middle of the city (a former convent). I gave the 17 sketchers who stayed behind tips and tricks on how to make and improve their perspective skills, while drawing in the wild.
For that reason I could not draw as much as I liked to, but that was okay, I think I fulfilled a real need.
The drawing you see above was the demo that I did on location.
