I'm knitting away at the Noro Sekku yarn in odd moments of the day. I'm knitting from the centre of the ball, so I don't know what's coming next. The stripes should get narrower as the triangle gets wider. All of that gives it enough interest to keep me happy.
And when I get tired of dealing with twisty snarly slubby yarn, then I know it's time to put it down and do something else.
