Because sometimes the best way to figure out a messy plot is to knit something small and quick. This little "hurricane hat" seemed appropriate.
And then it's just like those first 100 pages of writing -- all experiment and hope...and then found ill-fitting, so unraveled to make room for the way you should have written it. I finished the hat based on the instructions -- but it was too large, and I would have preferred using double pointed needles for more control. So unraveled it was. Still I don't mind starting over. I know the pattern now and know how to make it better. Like writing the second draft.
