Blood Background Effect in Photoshop CS2

I was messing around in photoshop making a gimp care bare (as you can see in the background of my photoshop. LAWL.) and I came across a nice way to make a blood background maybe for a signature or avatar or what not and I'll teach you how to make it!

Okay, you're going to start off by creating a new 5 inch by 5 inch document.

Alright, go ahead and take your paint bucket tool select black or blackish color and fill in the new document/layer with black.

The picture is selecting clouds but what you're actually going to do is select fibers instead of clouds.

Now your picture should look something like what I have, you should leave the defaults for a look like i have or you can play with it, it really doesn't matter it will still look like our base idea.

Now go ahead and go back to filter then render then difference clouds, you can do this once or for a better effect do it twice.
(check picture)

Okay now your going to change the hue and saturation, but don't fret I have the settings for that right here, or you can play around with it a little and create your own little effect.
Once you're done with that you can add text or some wierd little picture because I know how freaky all you instructatards are ; P just joking! But yep thats the basis of it all and it's really simple and easy to understand!
