This knife painting was done using acrylics on an old canvas from a painting idea I never developed. The dark blue acrylic paint already on it would work well in the rocky sea shore scene I was now going to paint, both as dark shadows in the sea and in the rocks.
I started by roughly marking with brown where the main rock formations would be. It may seem random or unplanned, but I had a strong mental image of my intended composition, derived from on-site sketching and reference photos.
Then I painted the sky area loosely with white, in short horizontal knife strokes. I let some of the existing blue show through and didn't try to make the white paint consistent in thickness because I wanted it to appear as clouds, not an overcast sky or fog.
