Nowhere does the author speculate that possibly, this is because the hobbies have gotten more popular and possibly more people are knitting or perhaps they're generally more interested in higher quality/more sustainable wool....
Too bad I am also not a subscriber; now I won't find the really expensive ways to knit. Do you need a golden thread?
My wife sews, and she has a small yarn collection as well, but never really got into knitting or crochet. I nearly had to contain my laughter when my mother told me that it would save us lots of money.
Sure. It costs more in fabric to make a shirt than to buy a shirt, and that’s not getting into machines. Look at us save!
Hobbies are for fun. Making things for yourself is, more often than not, crazy expensive.
