The first step is to create a file or select an image file that you want to use as a brush. You can use most common image file types to create your own brushes including JPEGs, PNGs, GIFs, and Paint.NET PDN files. If you plan to create your own brushes from scratch, set the image file at the maximum size that you will use the brush.
