I made a quick drawing on my Moleskine (Plain black hard cover Notebook 192 pages) on site which i finished in the plane back to France (Winsor & Newton watercolour).
The Chief Cabin Crew came and had a quick chat with me on the pleasure of drawing asking me how to find time to draw even in the busiest days.
I gave him a few reasonable advices and he was kind enough as to offer Champagne to me and my whole family… though we were travelling in economy class :).
