Step 11 Create various repeating patterns in Illustrator and place them on your artboard in Photoshop. You can vary the sizes and orientation to make the patterns interesting, or change their colours to add some contrast between designs elements.
Step 12 Make individual layers for each pattern you’ve created. Place them inside the ‘Foreground Elements’ folder if you want them to appear on top of other design elements, or in the ‘Background Elements’ folder if you want them to appear on the background. This technique will create visual depth when you apply Layers Styles such as Drop Shadow and Outer Glow on selected design elements.
Step 13 To help define your foreground layers, apply Drop Shadow and Outer Glow in the Layer Styles palette. The default settings are good enough but feel free to experiment and change the opacity, angle, distance, spread and size of the layer styles you want to use.
