I personally took Wilton courses and went to culinary school. I just figured it would be best to learn all that I could. I think the advantage is that I don't limit myself to decorating cakes. I can ulimately do it all cakes, pies, cookies, quickbreads, candy, pastries, bread, and eventually I plan to even do a little catering. I honestly feel like you should try to learn as much as you can, so that you can find your niche. When cake orders are down...I can still make money from other items. This year also plan to offer gourmet gift baskets. With that said...I still plan to take future courses. I can always learn something new.
