When I bought this book, I assumed it was for the beginning corset builder who already had strong sewing and pattern skills. I was wrong. This book is for absolute beginners, and assumes you can basically sew a straight line and that's it. It does do a good job of explaining the different components necessary in a corset (busks, grommets, different kinds of boning), and the instructions and diagrams are very clear, but I was looking for something more advanced. I will update when I have found better corset book options!
