I recently received a beautiful book by John Huxley titled: Fetishcraft. It's the best book of its type that I've ever seen: a great primer on making your own custom fetish gear in leather.
I really like that it's more than just a how-to manual. The chapters begin with the author discussing different aspects of fetishism and the BD/SM sexual experience - almost a philosophical overview that frames the projects.
Production processes and techniques are spelled out clearly. The level of detail and the variety of projects makes this book a treasure trove of information.
...and even zentai suits made of spandex.
There are patterns and tips for making bondage-style hoods in leather.
(I always love seeing how different people approach the problem of making a tight-fitting leather envelope for the human head out of what is essentially a flat material.) Many of the projects covered in the book could be adapted for latex construction as well.
Lots of creative ideas to get your mind going when it comes to customizing your designs to make them truly your own.
Some of the projects are more simple, like the fist mitts,
a ball gag,harnesses,
and a cock sheath!
There are some pretty complex projects here as well, including a very thorough description for making weighted, plaited floggers - from cutting the strips of leather you'll need, to the turks-head knot used to finish the end of the handle.
Overall, I'd highly recommend this book for anyone interested in leathercraft, making their own gear, or even making things for others. It's detailed, thorough and organized, offers a comprehensive overview of tools, equipment and techniques.
