I love this piece!
It’s become one of my favorites and I will make another for myself as I always keep my samples hugged in air tight containment - not my sweater drawer.
I’ve used a 100% Aran weight Wool. It would be appropriate to use a Highland or Micron Wool Aran too.
The cabling is simple enough, as is the cable on the collar.
You’ll have to focus on the Raglan and Yoke shaping - but I’ve charted the written instruction.
I’ve included charts for pattern layout and repeat.
