Tools needed: a poplar leaf, dyes, white paper and cotton.

1. Collection and rough machining: collect leaves with petioles, but also pay attention to collecting leaves of various shapes and colors. Collect more leaves of each kind, and also collect more leaves of the same kind. Don't collect large leaves (too many roots are difficult to cut when using), and don't collect rotten, damaged and ovulated leaves.

2. Finishing and pressing: put the collected leaves into a book and flatten them with a book. The purpose of pressing is to make the blade dry and smooth, that is, to determine the shape of the blade, but one night is enough, not too dry, otherwise it is not easy to cut.

3. Composition and naming: Composition is a key step in making leaf paintings. The content of leaf painting is very extensive, but we should pay attention to the rationality, ingenuity and novelty of composition. Each leaf can stand upright, upside down, tilt and hide from each other, so consider it in advance.

4. Fixation: Stick the placed leaves on the paper you want to paint, and use latex instead of glue, because latex dries quickly and sticks firmly, and it can keep the leaves clean.

The trick of leaf sticker is to summarize the basic shape of the sticker first. The basic shape is a large outline. To simplify a complex image, we must first summarize the basic shape of a person with simple geometric figures, and then process it on the basic shape.
