How much rope you need depends a bit on what types of ties you want to do and who you are tying.
For chest ties and hip harnesses: Measure a loop around the fullest part of the hip. You'll need roughly six times the hip measurement of the person being tied.
For full-body harnesses: Measure a loop from the shoulder, down between the legs, and back to the shoulder. Body harnesses will need roughly six or seven times the shoulder-crotch loop measurement.
If you're just getting started and aren't sure if this is something you're going to do all the time, we suggest our Curiosity, Robust, or Value-Line kits.
Know you're into it but just getting started? Try our More Than Curious, Extra Robust, or Midori Essentials kits. Remember- you can always add to your rope kit as your skills and personal tying style develops.
