I learnt to knit from my mother when I was about 10, then stopped knitting in my early 20's and didn't start again till 4 years ago... a 30 year break. In the last four years I've learnt a lot, mainly by just doing it, but also from googling for information on the Web.
I knit as often as I can - in the car (as a passenger), train, waiting rooms, watching TV, etc - I'm lost on the days I don't have time to knit. I really miss it.
When I'm not knitting, I'm planning - dreaming of what to knit next, and particularly working out colour schemes. What you can do with colour fascinates me.
This sounds pitiful, but I also dream about knitting and yarn... I sleep talk and quite often my poor husband has to put up with weird discussions about knitting, in the middle of the night.
