Leaf painting is a painting or printing artwork on natural leaf veins. We first put the leaves in to water long time and in suitable temperature to ferment the leaves. The surface of the leaf is very easy to be removed after ferment. Then the leaf veins are put into boiled water for 3 hours to make sure the veins can be kept for a long time. After dry the leaf veins in natural condition, some special glue water is painted onto the veins. Then, dry the leaf veins again. After all above, veins that can be painted or printed are finished. Then, we will paint or print on the leaf.
