Below zero again last night. But here in the house I'm warm. Here in the house, lying in bed at night, I'm snug and warm beneath two heavy wool blankets.
Don't know how many years back it was that I got onto wool blankets. Insist on 100% pure wool. And get thick, heavy wool blankets. And pile them on, one on top of another. There is nothing quite like wool blankets on a bitterly cold winter night.
