Learn how to make this icon, using Adobe Photoshop CS 8 and some brush tools. Some moderate knowledge of Photoshop is required in order to do this tutorial, and as with all icon tutorials, it is merely a guide - it is perfectly alright to copy this icon exactly the first time to learn the technique, but otherwise the icon should not be replicated.
