Procreate’s Streamline feature is an easy way to make your brush strokes smoother. To enable Streamline, click into the Brushes menu in Procreate, select the brush you’d like to edit, and click into the Stroke settings. Second from the top, you will see the Streamline setting—drag the slider to your desired percentage (100 percent will give you the most streamlined stroke possible) and start drawing smooth lines. You can repeat this process for any other brushes if required.
