Experiment by painting with water and adding the colours to roam and freely create their own shapes. Using the lightest colour to begin the artwork - moving onto more colour in the water for the orange - then the brown has the least flow of water. This experiment shows how pools of water react - how adding additional colour dabs to one area may transform other areas of wet paper. This wet on wet technique is the perfect example for you to observe as the water has its own creative quality. It works best for these trees.
