It helps a lot on what you should shop for corset making. I haven't build my corset yet but I have understood how, and with the dvd "The Express Corsetry Course" I believe that it will be a success. Overall a cohesive book. I would prefer coloured pages :)
This book has some good written information on corset making. However it was not what I was after as it included no photographs and just a few diagrams which were not so helpful. Not a bad book but I know there are better available.
