There are a lot of ways to create custom patterns in Illustrator, but one of the most popular ways is to use the Pattern tool. The Pattern tool can be used to create basic shapes and patterns, as well as more complex designs. To use the Pattern tool, first open the Pattern tool palette in Illustrator. Then, click on the desired pattern you want to create. The Pattern tool will open up and allow you to select different parts of your design using different tools. You can also drag and drop pieces of your design into the pattern area to make it more easily customizable. Once you have selected a pattern, you can start creating your own designs by clicking on one of the available templates or by dragging and dropping pieces of your design into the pattern area. You can also change some of the properties of your patterns if you want them to be more specific or unique.
