Is there anything specific that you want to learn? If there is let me know and I will help you find a tutorial.
What page is it? You can learn cake decorating for free in Facebook- search for Decorator Secrets and in youtube. Just type the word Decorator Secrets when you are logged in to Facebook then type www.youtube.com then search for any tutorials you want to watch.
I have many more but you can also look up "1000 tutorials and more" or "Just cake it tutorials" on facebook. They have a very large list.
