Used two colours instead of one as stated in the instruction. The multi-coloured yarn is used for the patterned parts, the solid yarn for the plain knitting.
Plain knitting was done on my knitting machine.
To my surprise, two skeins were sufficient for this garment.

I worked the yoke in one piece with short rows to achieve the deeper neckline at the front.
I modified the separating stitches next to the button band by working slipped stitches instead of lace pattern.
