As it becomes apparent, this stitch pattern does not want starting from the neck, so to say. I discovered a minor mistake and decided to frog a couple of rows. I took the shawl that has quite grown from the needles and noticed that there is an angle in the beginning at a wrong place. It appears that the first beginning (from the tip) was better, after all. So I see no options here, I will rip it and start all over again.
I am not problematizing ripping, nothing extraordinary here. In any case, I have learned something.
