In general I think a law degree accepts any combination of subjects (however, this will be different for other degrees). But for law, History, Politics and Textiles should be fine.
I would recommend choosing subjects that you are likely to achieve high grades in, as this would increase your chances of entering the higher ranked Universities.
Whilst textiles is not an essay based subject, I do not think it would be seen as weaker if you achieve high grades. It is also possible to demonstrate your interest in law through work experience, volunteering and other events.
Hope this helps.
