For the benefit of Andie who is contemplating making one.
This is the "Hot Lava Cardigan" from the Blue Alvarez site (see link in sidebar under shopping.)
I knitted this a couple of years ago (or was it only last year? From the condition of the spare room I'd say last year). In fact it was the project that got me back into knitting again.
Blimey look at that, then I had no hair and a waist, now I have no waist but I do have hair.
