I've been making experiments on small canvases before starting the final painting, for many years now. I like to try out lots of ideas before I do the final piece.
Selling them came quite by accident. I was asked to donate a painting to a charity auction and it was suggested that I might like to give one of my preliminary canvases. To my surprise it made a fair amount of money so I have been selling them ever since.
Currently there are three for sale from a recent painting, 'The Wasp and The Ring' at the Babylon Gallery, Ely.
You can also see the final painting and preliminary studies on my Instagram and Facebook posts.
