Materials Paint Step 1 - Holding the brush A steady hand and accuracy are essential when you are trying to paint where two colours meet. Use a small brush and narrow the width of the brush by turning it on its edge to give greater accuracy. Hold the brush firmly between your thumb and forefinger for maximum control. Step 2 - Loading the brush In order to give greater control over the flow of paint load the brush so it is about 1/3 full with paint. Carefully wipe the excess on the edge of the paint kettle, allowing the extra to run back into the tin. Step 3 - Working towards the edge Start slightly away from the edge and gradually work your way closer and closer. Squeeze the paint from the brush slowly. Step 4 - Drawing the brush down For a vertical edge gradually draw the brush down in a continuous stroke. Remember you have to paint to a wet edge.
