The wool thing is mysterious, because I keep hearing about sheep farmers losing money on shearing sheep because the raw wool price is too low, and then I went round a fabric shop the other day and it was all polyester, I don't get why.

Polyester can be made 24/7 365 while wool comes in batches. Also, regardless of how low wool prices are, it will be more expensive than polyester components as the sheep require being fed and what not. Maybe polyester prices are affected by Hormuz closing????

There's many grades of wool and the coarse ones really are very cheap. So cheap as to be used for carpet in government schools (in NZ/Australia).
