Step-by-step explanation:
When moving from an existing to a desired texture in art, the basic decision is to determine the type of texture you want to create. You can choose to create a rough texture that imitates the feel of something like a rock or wood. Alternatively, you can opt for a smooth texture that gives a flat surface an even and polished appearance.
A rough texture can be achieved by utilizing techniques such as layering paint with a dry brush or using a palette knife to create bold strokes. On the other hand, a smooth texture can be achieved by using a brush with soft and even strokes along with thin layers of paint.
For example, if you wanted to create a painting of a mountain, you could use a rough texture to convey the ruggedness of the rocks and cliffs. Alternatively, if you wanted to paint a calm lake, you could use a smooth texture to depict the serene and glassy surface of the water.
