So despite my conviction that superstition is really foolish, and a waste of time, I'm discovering that I perhaps hold with superstition more than I thought I did.
Today I finally hit the part in the sweater where it goes from being a ring to being a tube (i.e. the length of the knitting is greater than the difference in radii of the circular needle & the sweater). And I'm still having "hmm. This is considered a bad idea." thoughts.
I'm just going to have to see this as a challenge - I WILL prove that stupid superstition wrong. There's no such thing as the sweater curse! At least... no actual curse...
And for those of you who care - Ashkeyana has a bit more to say.
