This is a very easy and fast one piece, top down, raglan.
I think it suits mohair yarn very well. But also a soft chunky wool or alpaca would be very good.

I worked it all one piece to take advantage of the multi coloured hand dyed yarn. This way all the sides match up and you can see the natural progression of the colours.

It should fit a bit loose on the bust and upperarms, because the ribbed waist band will bring it in tight, for a fitted look. Sleeve cuffs are long, so you can roll them back as needed.

The collar is BIG. You can wear it draped like a cowl, or pull it down over your shoulders for an off the shoulder look. It is actually big enough to wear as a type of hood, if you would want to layer it under a jacket.
