Canadian Art

When did knitting become an artform? I mean I know there are some really cool knitted works, and like yarn bombing is pretty cool.

But the knitted mile? I dont know if I can classify that actual work as an artwork - but I suppose since there are other knitters involved it could be some sort of compilation work or performance art?
I should tell that to my grandmother...
It looks really warm at least.

It's an artform that I could do though so maybe I shouldn't be complaining about it - I should just not finish my scarves when I make them and instead keep going  - will that make me famous? Celebrity lifestyle as a result from knitting? I'm on it.
