Query: Great basic reference

I've been making soap for a year now, and this is the first book I bought. Overall, it is a great source. I read it three times before I even tried to make a batch. I would recommend thoroughly reading this book, but do not take all Ann's advise as law. For example: she says that your temperatures must be between 95 and 98 degrees or your batches will fail. Not true! And she says you should not make batches smaller than 6 pounds. Many people make 1 pound batches with no problems. For most people, this is just a hobby and what will they do with 6 pounds of soap, especially when you want to make a few different kinds!
