The Shapeshifter begins with a round yoke, first transitions into a raglan construction and finally into a diamond pattern. The sleeves are worked in a ribbing pattern.

You should already have some knitting experience, this should not be the first sweater you knit.
I explain the individual patterns, there is also a photo tutorial on how you can work the diamond pattern quickly and without a cable needle.
There are also tutorials for a special type of increases and double stitches.
