Substituting kfb increases for M1: stretchier and easier to keep track of.

Used Jeny’s Surprisingly Stretchy bind off, which seemed to work OK.

I weighed the leftovers. I have 30g of yellow (MC), 44g of orange (C1) and 23g of green (C2). Enough for a matching hat!

So it turns out I made a mistake with this. I kept going with the short row section til I got to the end of the middle section. Just goes to show how I was operating on autopilot. Still, I like it this way -- it has a bit of extra length.
