Crochet cardigan with a round yoke.

For this model, you need not very thin threads (for example, 300m/50g) (otherwise the lace part will be very revealing) I started with an elastic chain (I really love it, first of all, it is elastic - like in store-bought sweaters, secondly, it has a beautiful edge, and thirdly, it is very convenient to crochet filet 1 to 1) and the yoke itself:

notice how conveniently the corners are made in the armhole! and this is how it looks in the original:
the corners are as shown in the diagram, we knit after distributing the sleeves, I have 16 "branches" on the sleeves with 3 and 5 on the back and front, marked with pins - where the pins are, we knit the corner, it is very convenient to knit with corners, the product acquires the necessary shape
