Quick Lesson -- Dargie took the brush from the women's hand borrowed a painting block and some oils and started to paint.In half an hour his quick, sure strokes, had transferred the winter scene to the painting block.Home in his studio today, Dargie walked across to a large canvas of cows in Windsor Great Park - "I just bought it for its big the little painting of Chelsea to the well."Just a quick painting lesson to show a friend how to capture a little atmosphere," he said.
