Have you ever found yourself wondering, “How do I apply a gradient to a stroke?” or, perhaps, “How do I make a gradient follow a curve?” Unfortunately, there isn’t a simple solution in Illustrator for these questions. However, there are some ways to achieve the appearance of having a gradient follow the curves of a path. In this example, we will be looking at how to apply a gradient to a path as a brush stroke, by creating an Art Brush based on a gradient. This is intended for intermediate Illustrator users and assumes the user has a basic working knowledge of Illustrator tools.

Tools/Functions Used:

• Rectangle Tool
• Gradient Palette
• Expand Function
• Transform Palette
• Brushes Palette
• Brush Tool and/or Pen Tool

When asking “How do I apply a gradient as a stroke?” you’ll often be told that the solution is as simple as expanding your stroke into a shape (select your path, and use either Object>Expand or Path>Outline Stroke) and then applying your gradient. This is all fine and dandy, unless you expect that your gradient is going to following the curvature of your original stroked path.
