Here are some words of wisdom from Mary Thomas in the Preface to "Mary Thomas´s Knitting Book", originally published in 1938:
"All things are possible in knitting. Women knit almost by instinct, men now for pleasure, though not so long past it provided him with a means of livelihood. (...) Knitting should be done thoughtfully. It should not be hurried. That is its charm to our generation, who live surrounded with a wild helter-skelter of speed. It is creative, and that is its supreme satisfaction. If things go wrong don´t get impatient."
