The Art of Watercolour magazine
I wonder if you are familiar with this magazine? It is a beautiful one, and reputed to be the very best watercolor publication available. It's published in English, and there is a French edition called "Pratique des Artes". My work has previously been featured in both, and I was thrilled to be asked to send some floral paintings for a special section in the September issue.
Luckily I had taken photos of the steps in painting "Sunflowers" for my students, and so I was able to send those photos to the editors. If you don't have a subscription, I hope you will be able to find the magazine at a bookstore.
