I absolutely wasn't disappointed. Corset Making is perfect for beginners and probably experienced corset-makers as well.
Julia Bremble shares a lot of handy tips that she has gained from experience, some of which I have never seen elsewhere but which will give a much more expert finish, even for the beginner. There are detailed photos of the construction process.
The fitting section is specialised to corset making and includes techniques that I've not seen in other types of fitting.
