Process art is just like playing with toys, but instead of dolls or blocks, artists use things like paint, paper, and glue. They make art by enjoying the process of making it, not just the finished product.
Like when you play with your toys, you might start by picking out the ones you want to play with and then figuring out what you can do with them. When artists do process art, they start by gathering materials they want to use, like different colors of paint or different textures of paper. Then they start to see what they can create with them by experimenting and trying different ways of putting them together.
For example, an artist might start by putting different colors of paint on a canvas, then using a brush or sponge to mix them together and see what they make. They might also use different tools to add texture, like scraping the paint with a comb or adding salt to make small bubbles.
The important thing about process art is that there's no wrong way to do it. It's all about having fun and being creative. Even if the final product doesn't look like anything in particular, the artist has still learned something and enjoyed the process of making it.
