I learned ho to knit from my mother when I was about 8 or 9 years old. I did some scarves and pullovers for my teddy bears back then and on and off during my teen years.
I started knitting again at the age of about 25 because I didn't like any of the pullovers I could buy in the stores and decided I could easily make some myself.
I taught myself how to knit socks from various basic patters at the age of 30. Now, socks are my favourite projects, even though I do knit other things from time to time.
