Create a pencil or sketched style in photoshop for websites

I found this image on the internet:

I want to use this style on some icons. Is there anyone familiar with this style and do you have an advice for me?

Answer

Pull a regular icon into photoshop, then Filter -> Sketch -> Graphic Pen.

This will do your sketching look, then you probably just have to free-erase some edges, and maybe apply a light outline and you're good. Easiest way I can think of
