Using Charles' pattern mounted on a cardboard tube I made this example out of 3/32" cotton cord.
This is available in my Zibbet marketplace.
You can see that the knot is a plain weave turks head of 7 parts and 8 bights. The carrack bends (there are 8 of them) appear in the inner part of the knot offset from each other. This example is rather loosely tied.This is available in my Zibbet marketplace.
