Painting with a knife is fast, physical and very hard to overwork — which is exactly why it suits an evening like this. Paint goes on thickly, edges happen by accident, and the result has a surface you want to touch.
The subject is coastline in weather: a horizon, a sky doing something, water that is not just blue. You choose the mood — grey and wild, or late sun on a flat sea.
This one is louder than the other evenings. It is also the one people are most surprised by, because a knife makes marks no beginner could make with a brush.
