Last night, I found a screw-up in an early row of a fairly long scarf. I was briefly heartbroken (I'm starting early on holiday presents), but then I did the most liberating thing: I started over completely. I was able to improve the pattern a bit, and really think about the direction I wanted to project to go. I also got much further back into the scarf than I thought I would.
It's rare in life that we get a complete do-over. Thanks knitting!
