It takes a lot of work (a lot of guesswork!) to get a new pattern to work properly. In this case, I just messed around until I felt good about what I was doing. I wish a had a pattern to share, but since I improvised, I have even more work ahead of me to back track, retro design and carefully count out what I did to make it happen in the first place.
The most important thing is that I ended up with a pretty fluffy cowl that feels nice and looks great. :)
