The first was how to knit from scratch, this one is choosing a style later. There are two core styles - plain and purl and for purl, there'll need to be a different YT. There's nothing spurious in this ... I was taught these things in 6th form, year, grade by an enlightened man who was otherwise trad. Boys were taught cooking too, girls the internal combustion engine and basic car care.
The trad roles applied too but there were some of the other short courses.
