I few years ago I knitted a mohair cardigan/shrug thing, it's beautiful but waaay too large. I realised halfway through but was committed then. I wore it a few times but don't now, so I was thinking maybe I can deliberately shrink it in the wash and then I might wear it again.

Do I just put it in a hot wash?

It's not going to be a major issue if it shrinks irregularly as it is really 'free form' anyway, and seeing as I don't wear it, nothing will really be lost.

Any thoughts?
