Photoshop Tutorials

Create a new document of any size you want. I made mine 600x600

Now go to Edit » Fill

in the box that popup, select "Pattern" for "Use", and in the Custom Pattern option, select this pattern (CLICK TO SEE SCREENSHOT). Then click OK

Now go to Filter » Distort » Wave

Adjust your setting so its similar to mine: VIEW

Now just hold down the CTRL key, and press the "F" key 10 times (reapply the wave effect 10 times). Now you should get something very similar to mine on the left.

Now to give it a little bit of color, you can use the Hue and Saturation option, Image » Adjustments » Hue/Saturation. Make sure you check the "Colorize" box. Set the "Hue" bar to: 210, "Saturation" to: 14, leave the Lightness at 0.

Next, to make the image a little sharper, go to Filter » Sharpen » Sharpen

There you go :)
