The new skill of laddering down and re-knitting is wonderful. I've fixed one main cable cross and three miscrossed minicables. The minicables are reversed in direction going down the scarf, so it is easy to miscross even when paying attention. (I also failed to fix the edge of the seed stitch border, and had to cry uncle for that part). So even though this is like comfort knitting -- I really like the cables and I have the pattern memorized -- I'm still learning from it.
