It is weather for woolies, the season when we are grateful that sheep grow such wonderful fur. Wool in its natural state is rather waterproof and woolen fabric has the property of not losing its insulation when wet. The kinky texture of wool fibers traps lots of air, keeping us lovely and warm. I would never make it through the winter without wool!
Irish fishermen knitted heavy weatherproof sweaters to keep them warm at sea. Each village had distinctive patterns, which allowed for the identification of poor souls washed overboard. At least their bodies could be returned to the village of origin.
Today I am wearing a natural cream-colored wool pullover with all manner of fancy cable stitches. It has chevrons, split cables and cables with "popcorn" in the places between the cable crossings. My mother knitted it for me when I was in high school and somehow it has lasted out the decades. I think of her when I wear it.
