The cardigan is knitted from the top down, according to chart.
First, work the back yoke, where you continuously increase stitches to shape the oblique shoulders.
Then pick up and knit stitches along the oblique shoulder edges for the front pieces, that are worked separately.
Back and front pieces are gathered under the armholes, and the body is continued and ends with a rib edge.
Pick up and knit stitches in the armholes for sleeves knit these in the round.
Finally, pick up and knit stitches along the front pieces and knit the front edge in rib at the same time as it is knit together with the front pieces.
