Return to the beach of Chay in Royan, for this drawing improvised on the sand. This time this project will be in the form of a square. The idea here was to make a fairly massive fresco on a fairly simple assembly of bubbles of different sizes. An outline with ornaments will frame the whole to pose the drawing. A lovely couple will come to visit me on the beach that morning and lend me a hand for some of the filling. They took the opportunity to be not far from there, to come and see me following a publication that I had just made on social networks to say where I was. With this helping hand, it still took me more than 3h30 to come to terms with this sea effect painting.
