Mucking about in craft subjects is a slightly different problem, than in academic subjects.
In most things setting by academic ability, means at least the top two sets do somework, some of the time.
Unset, textiles is treated as a doss by all, but a few DC, who really like making things. They are hard groups to disapline and all abilities are tempted to take the piss.
This is magnified by the fact the pupils know, school doesn't value the subjects either as they aren't time tabled enough time to finish anything.
This is very sad because practical subjects are valuable not only for some career paths, but for fun and relaxation through school and adult life.
DD1 has no intention of going to art school, but is doing A level art to stay sane, after finding GCSE a blessed (if hard work) release at GCSE.
If they were able to enjoy textiles, DT etc further down the school I think many other DCs would do the same and we wouldn't get school is forcing my A* DC to waste a GCSE on art/DT threads.
