Translation Request – Atelier to nani IRO Sewing Closet shirt P

I was asked to translate the instructions for gathering of the collar in this shirt P, found in the latest nani IRO sewing book. There are 3 variations of this pattern – 2 of them are dresses (N and O)  and the last one is this shirt P. All of them have similar instructions for steps 1-6, so I am translating them here for you.

These translated instructions are for steps 1-6 found on pages 79-80 of the book Atelier to nani IRO’s Sewing Closet.
