I am new to this website and need some help with an armhole for a sleeping cover for a 30 cm doll. The original pattern is in French. I am not sure if I got the English translation right.

I have 46 stitches on the knitting needle. Then I get to the following instruction:

For the armholes: divide on each side, every 2 rows: 3 times 2 decreases then 2 fs 1 decrease

We get 30 stitches.

The French version is: Pour les emmanchures : faire de chaque côté, tous les 2 rangs : 3 fois 2 diminutions puis 2 fois 1 diminution.

On obtient 19 mailles.

I can’t figure out how to get from 46 stitches to 30 stitches. I first thought the instructions meant to bind off 2 stitches on the even row number for 6 rows and then decrease 1 stitch for the next two even row numbers but my calculations does not get to 30 stitches. Can somebody please explain how to do this.

Thanks.
