How to Make Corrugated Cardboard (Any Color)

This tutorial is a littler more involved than the basic cardboard, but it can be easily made into an action to be used wherever you'd like.

First set both the foreground and background colors. Generally I set the foreground to the color I'd like and then the background to a shade darker. Fill a layer with the foreground color and go to Filter -> Render -> Clouds. The color of the clouds will be your background color.

On the same layer go to Filter -> Noise -> Add Noise

On the same layer we are going to use the Filter Gallery:

Under texture choose "texturizer" and use the following settings:

Now make a new layer above and fill with the foreground color.

We are going to use the Filter Gallery again, this time under Sketch choose "Half Tone Pattern." The "size" will determine how wide the corrugation is. Also, the colors you have selected as the foreground and background colors will be used to make the "stripes."

On the same layer set the blending mode to "Darken" at 90%.

Duplicate that layer and change the blending mode to "Normal" at 75%.

Let's add a little more texture to the top layer by going to Filter -> Distort - > Ripple

Duplicate that layer and to the new layer go to Filter -> Other -> High Pass

Set the blending mode to "Soft Light" at 75%.
