And a question: What have you learned to do that has marked a definite change in your knitting life?

Learning to knit a jumper (sweater) by measuring the recipient & without a commercial pattern or software is the best thing I have learnt. It finally "clicked" for me when I read "Knitting in the Old Way" by Priscilla Gibson-Roberts.
