Here is the threading pattern and a weaving instruction for one of the birka knots, which I used in the peace "tablet weaving birka knots" [link]
The letter f means weave the amount of cards forward, b means weave the amount of cards backwards.
Every row in woven twice. (Each line of dots is one turn)
Remember, I didn't design the pattern. I only made a easier weaving instruction.
I found the pattern here on the loomy bin [link]
