Roy Holding was our demonstrator this month showing us how to use pastels with acrylics to make an interesting picture.
He uses mount-board to give a firm surface and he treats it with a chalky mixture before drawing the subject on it. Then he reinforces this with waterproof ink. This fixes the drawing as he uses sprayed water to give texture to his work later on in the process.
Using acrylics he painted in some of the picture and then sprayed it for an interesting effect. The dribbles are then used to give another feel to the foreground. He then used a pointed stick to 'draw' some trees in the background and sprayed them gently to enhance the leafy look.
When the paint was dry Roy took to pastels to finish the picture, which was very effective and gave an atmospheric look to the final scene.
