He is not a terrible beast at all! The input of the needle into the stitched fabric is always from the outside, the output from the adjacent loop from the inside so that the arch remains on the wrong side. And adjust the tension so that the seam resembles a stitched fabric.
If you want to make the entire seam a single thread, then the length of this thread should be three times the expected seam + margin on the tail.
