I’m following the instructions for 37.5” and using slightly bigger needles.

Have replaced M1 for KFB as I prefer the look.

For the eyelet increases: (centre section)
K2, (m1,K5) x 10
(M1, K6) x 17
(M1, K5) x 10
M1, K3
Based on counts from this calculator.

Until I was pointed in the direction of the calculator, I was not especially loving this pattern. I prefer a pattern tell me exactly what to do (if I wanted to have to calculate bits, I’d rather be knitting my own design) instead of having to stop and start while figuring out the maths (or, in my case, procrastinating about doing the maths!)

After getting the increases sorted, it has been an easy knit and actually quite enjoyable. As the needles were already larger, I used the same 6mm for the bind off but used a stretchy bind off - k1, (k1, k2tog through back loop), rep to end.

Body bound off with 134g left for the sleeves.
