You know... since it's going to be felted, mistakes aren't going to show, right?
This would be a good time to practice knitting in a different style... like Continental?
Or practice knitting without looking... This is a great trick for when you're watching a movie!
And if you make a teensy mistake, who's gonna know. And the frustration from trying to learn these new skills will surely keep you entertained, AND make you GLAD it's only stockingette!
