I made a full beginner friendly tutorial for this sweater over on my YouTube Channel.

YouTube Video Tutorials
The series is for complete beginners, no prior knowledge required.
Part 1: Learn how to knit, supples, gauge swatch, collar and yoke
Part 2: Sectioning off Sleeves, Body, Italian Bind Off
Part 3: Knitting Sleeves, Cuff and Blocking

Instructions PDF on patreon (free)
I also made detailed instructions to follow along. Use the instructions together with the videos and vice versa. The instructions are free to download on my patreon page. They are not a pattern, but instructions on how to make your sweater according to your measurements. A pattern for my version of this sweater will be released soon as a patreon exclusive for paid members.
