I have a 'plein air' harbour painting on my wall at the moment, and it lifts me when I look at the bright colours and splashes of paint. I think that these are 'slap happy' paintings.
This Bondi Beach is one of my favourites: painted on a large sheet of watercolour paper, which I then mount onto canvas. I will be describing my 'mount' technique soon. I think it's a winner, so I'll share. :)
