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.
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."
