As Ben Elton so eloquently put it, you know it's cold out 'when your nipples are bigger than your nob.' Now, I don't think many nob-owners will be rushing out to buy this girly beaded scarf from Bishopston Trading, but that doesn't mean they shouldn't buy it as a Xmas gift. Although it ain't woven from organic cotton and doesn't carry the new Fairtrade badge for clothing, Bishopston says it is made by Indian tailors paid an above-average wage and guaranteed year-round employment. And since Bishopston's been in this business for a while, I'm inclined to believe it. £10 to you from here.

They have scarfs and many other things, from all over the planet. I have a few Christmas gifts coming in from them.
