Interesting and easy to knit.
The key is the fit. I recommend to check your measurements before you start. If this is to large the piece will fall off your shoulders.

I choose (for the first time ever) to use negative ease. This is knitted two sizes smaller than my bust size. Even though my gauge matched the given.

I have a very loose gauge. That’s why I changed to smaller needles much earlier, but in slow steps. All weight is held on the shoulder section. I liked the fabric in that area much more dense.
At sleeve size 30st I changed to 4mm needles, at 18st I changed to 3.5mm on the collar I used 3mm.
Shortened the collar to 10rows only. That’s why I used only 80st on the fronts.

The yarn reminds me a lot of Rowan Felted Tweed. I love the alpaca content which gives the fabric drape (together with the Rayon) and a cozy feeling.

It seems to me that there is a mistake in the pattern of the right front.
The pattern reads: “ …..short rows 5-11 Rep short row 4 seven more times, …” I guess this phrase is just copied from the left front pattern but makes no sense here. You should work (like the left front) until 3st before prev turn and turn.

Notiz an mich:
Ärmel in 3,5mm in kleinster Größe anschlagen
Ärmelweite 30M zur Nadel 4mm wechseln
Ärmelweite 18M zur Nadel 3,5mm wechseln
Kragen mit Nadeln 3mm arbeiten
Kragen nur insgesamt 10 Reihen
Frontblende 80M
