This is the most difficult question of the day. I have lots of the classes and have liked all of them except one. And, I know that exception had a whole lot more to do with me than the class or instructor. I really like their concept and I have learned so very much from all of them. Today, I am liking the quick tips from Debby Caffrey. Another day, it is the preciseness of Carol Doak and Angela Walters. I am glad I have a nice 'library'.
