The construction of this is really kind of clever. You take your measurements, then cast on and knit according to them. The whole thing is done flat, sort of an hourglass shape, then seamed together into a shrug. The “right” side is a simple 1×1 rib and the “wrong” side is simply purl 1, slip 1. It is going FAST!
I’m using Cascade 220 yarn and I’m loving how fluffy it is knitting up. Seems weird to be knitting with nice thick wool on 90* days though. Oh well.
