This texture is used all over the art community, albeit sometimes looks different.
The purpose of this tutorial is NOT to fully and completely emulate what you've seen; rather it's to put you on the path to be able to do it. You'll have to modify what you read to suit your needs: tutorials such as these require a bit of imagination at times.
Mind you, it'll always come out looking like I did it if you follow it to a T, but at the same time, toy with it.
I didn't have time to come up with a better thumbnail.
