I enjoy knitting these, I've done a fair few over the years now, and every one comes out a little bit differently. I particularly like this yarn, its a vintage undyed Welsh wool, no idea what mill it came from, but its a heavy two ply and really very similar to handspun in the way it behaves and appears. I think I have enough for one more hat on the cone after this one, will be sorry when it runs out.
Of course, the ideal is to spin my own yarn for these, but whilst I enjoy spinning I just haven't quite got enough hours in the day at the moment. Really want to improve on that this year if I can.
