Maybe I'm not a really committed knitter. It seems that a lot of knitters just knit, all the time, while they're doing all of their other stuff. I'm am not good enough at multi-tasking to be one of these people.
Maybe I'm just not dedicated enough. Maybe I'm still too novice a knitter that it hasn't completely consumed me yet. I don't know if this is a good thing or a bad thing. There's still a very long way to go on the jumper.
