New Classes

I have been working on some new classes to offer next month but I really wanted everyone else's input.  My plan is to teach a Food Gifts Class in December.  I was also thinking about Cookies.  What I would like to know is....What do you want to learn when it comes to cake, cookie and cupcake decorating?  Is there something you have been dying to try but not really sure how to go about it?  You can post your answers in the comment area or on our Facebook page.
