I was interested in a fancier knot I saw on a woven bracelet, but this was a good place to start. I thought it might make a nice start to a self-tie harness--it does feel great to pull on the ends and make it tighter!
Also it can make this pretty loop that would be lovely for attaching more rope to take it up around the chest or down through the crotch.
Here's hoping the sliding knots find some lovely safe adventure!
