Frame with shoulder straps, giving 3 points of support
This can also just be a design choice, but it also provides even more support.
This begins the same as the 2-point variant above.
This time bring the line over the shoulder, then straight down.
Connect to the top line with a Cow Hitch (or whatever other kind of connection you like). If using a Cow Hitch, do your first tail pull toward the outside of the body.
Complete the Cow Hitch.
Run the tail up around the back of the neck, then straight down again.
Connect to the top line with a second Cow Hitch. (This time doing the first tail pull toward the inside of the body.)
Run the tail up and over the shoulder.
In the back, bring the tail to the node and secure it with a Crossing Hitch.
If you have enough rope, you can begin creating your imbricated pattern right from here.
