Query: Some helpful suggestions, but mostly common-sense stuff.

I found the author's information to be mostly common-sense, and not very unique. She spent 50 pages on sewing technique, which, according to the title, was not the purpose of the book. What I thought was going to be an interesting section on what to take to sewing classes was disappointing, as you would need a moving van to take everything the author suggested. Overall, I would say it was not good use of my money or my reading time, and I would (conditionally) recommend it only to very inexperienced sewing "students."
