In reply to wilkie14c:
The craze for novelty Xmas jumpers started, I suggest, with a pash for Nordic sweaters following all the detective noir series coming out of Sweden, Denmark etc.
I picked up a fantastic Norwegian gansey last summer (made out of real wool not pure acrylic!) but so far it's been too globally warm for me to wear it. I'm looking forward to turning a few heads down the folk club eventually, but they'll have to turn the heating off.
