Thank you for the great lesson. It was quite informative to learn about the history of Graffiti first then was truly fun to try using spray can to practise drawing before actually making a piece for my own. It surely was really exciting to try making a Graffiti piece over a quite large canvas that you can take it home. I would like to suggest that you should roughly decide what you would like to draw in advance. I like to try it again when I will have a chance to be in Brooklyn, NYC.
