I learnt to knit when I was about three. I knitted random squares which I sewed up to make skirts for my dolls. The first thing I made from a pattern was a pair of trousers for my Action Man, and they're still in my doll box in my parents' house some 25+ years later.
You can see my knitting change radically between one leg and next. On the first leg I crossed all the knit stitches, and on the second leg I didn't.
I was given a choice between knitting trousers or a jumper. The jumper looked more difficult so Mum got that job. I was actually ordered to knit something for the doll to wear.
See, I'd saved up to buy the Action Man to be a boyfriend for my Sindy dolls. I got impatient and as soon as I had enough money to buy the cheapest one, I got him. Except, he was a Desert Action Man, and he had boots, a hat, a pair of shorts and a gun. I lost the shorts the same day I brought him home, and for some reason my mum objected to my playing with a Action Man who was nekkid apart from his hat & boots

I think my gran said something about it being disgusting. Hence being ordered to knit him something, and The Choice.
I think I was about nine or ten.
