This video tutorial shows how to create a very nice karada body harness including double coin knots.  MiShibari moves slowly so you can easily see his technique.

The karada harness can simply be decorative, or it can be a body harness used to anchor other ties.

This technique should be in your bag of techniques.

Enjoy the video after the break.
