Sweet Ambs is great. If you can get to PA there are two more great cookie decorators. Stephanie at the Hungry Hippopotamus in King of Prussia, PA offers cookie decorating classes. I took 2 with her already. She has a Halloween cookie class on Oct 18th. She posted that class on here and her website. The other place for classes is with Anne from Flour Box Bakery in Bellefonte, PA. She is also great. Hope that helps.
