It's really hard. Not the actual pattern, but the keeping track of the stitches and the yarn-overs and what row you're on is. I've undone my scarf three times. Right now my Frilly Frilly scarf isn't even on the needles.
I took this photo before I ripped it out, before I lost count for the third time.
Now I'm going to go and start again, in a silent room with no one talking to me so I won't get distracted!
