Info
The Paracord Sanctified Covenant knot is often used for bracelets, but can be used for other projects (like dog collars) as well.
Making the set-up for this knot is a bit different than with the normal Kosmetik 2.0. In the tutorial you can see how to start the sanctified covenant knot, how to tie the knot itself and how to finish it off.
