About a year ago I made a pair of mitts from The Knitter's Bible: Knitted Accessories with Cascade Greenland yarn. They have a lovely cable down the back, and are otherwise ribbed, giving lots of warmth and stretch. Greenland is Superwash, so there isn't much allergic reaction. I wear them to knit in the the chilly Buffalo winter, and love them.
Today my eldest placed an order for a pair of her own, mentioning that she's been borrowing mine because they are "so cool". I've knit for my teens before, and it's always a mystery what will be popular for more than a few weeks. Mitts seem to be a winner every time, but who would have thought my boho grunge daughter would be mad for cables?
