It must be the promise of the colder days - I cannot stop myself casting on for many different projects. Having just finished Boxy and Buttony, I've started a new oversized pullover. I've dug deep into the bottom of my stash and pulled out Noro Kureyon Sock that I must have purchased in winter 2009-10. One skein is not going to be enough, I know that, but with some stripes and an additional skein this is going to be a fast knit.
What is your must-knit for this autumn?
