I love painting with palette knives. It's an "art" in itself and I need to come back to this technique often - a difficult skill!
One of the trickiest parts is controlling the edges. By it’s very nature every knife stroke wants to be pretty sharp so I need to go back and deliberately soften edges.
I was going to go back and “knife” the sky also but I never did. I think I'll leave it as-is. Hmmmm.
