Does anyone know a decent how to manual on rope bondage techniques? I'm pretty well versed in your basic wrist and ankle ties, and I'm looking to move up to teaching myself more advanced techniques for my girl's benefit (this is difficult without said girl available on a regular basis, but I make do). Just looking on Amazon isn't giving me much help, the how-to books there seem to have wildly varying reviews. There's plenty of tutorials on the web, I'm just partial to books.
