Step1. Open a new document of any size, make the background colour transparent.

Step2. Select the Rectangular marquee tool and at the top of the screen set feather to 10px, draw a box on your screen from one corner to the next, you should have this:



Step3. For a background colour select something dark, I used this colour: #56004C make sure your foreground colour is black. Apply this:

Filter: Render: Clouds
Then
Filter: Render: Difference clouds; apply this about 10-20 times till you have something like this:



Step4. Go:

Filter: Artistic: Watercolour

Use these settings:



Step5. Create a new layer, in the layer panel click and drag the new layer below the current one.

Step6. You need to change the background colour again, this time I used: #780000

Step7. Go:

Filter: Render: Clouds
Then
Filter: Render: Difference clouds; apply this about 10-20 times.

Then go:

Filter: Artistic: Watercolour; use the same settings as before. You should now have something like this:



Step8. Select the layer that used the feathered marquee tool and apply a mask, to do this press this button that can be found in the layers pallet. With the mask selected you will need a good cloud brush, if you do not have this then a large Airbrush will do (this comes with all Photoshop’s)

You will also notice when you applied the mask your colours reverted back to black and white, this is correct, when working on a mask they are the only colours you can use, along with various greys.

Step9. On the mask with the colour black as your foreground colour you need to just press about a bit till you get something that suits you, if you make a mistake pressing ‘Ctrl + Alt + Z’ will take you back as many steps as you wish.

This is what I got using a cloud brush:


This is what I got with a large Airbrush:


Step10. (optional)

You will need to make a new layer and use the Rectangular marquee tool again, this time with a feather of 5px.

On the new layer make a perfect square, to do this hold shift before you press and drag you will notice the movement is restricted this is because Photoshop is making sure the marquee tool makes a square.

With this small square made you need to set your foreground colour to that you used first and your background colour to that you used second, if you lost the colours use the swatch tool to select to relatively close colours from your current work.

Now with the colours selected and the square still in place do this:

Filter: Render: Clouds
Then
Filter: Render: Difference clouds; apply this about 10-20 times.
Then
Filter: Artistic: Watercolour, same settings as before.

You will now have something like this:


Now duplicate the layer several times (as many as it takes to evenly space them across the page) To duplicate a layer you need to right click on the layer you want to duplicate and with the pull down menu that will appear press duplicate layer.

With the new layers drag each one using the black arrow found next to the rectangular marquee tool, to a place you find suitable and merge all the duplicated layers back to one. To do this select the top of the three layers (I used three) that where duplicated and press ‘CTRL+E’ until they are all one layer.

With that done go to the blending options and set them to darken or overlay. Using Darken I got this:
