It's getting chilly in Northern California. We finally had some rain this week, and temperatures are dropping a little. This may seem obvious; but, instead of flicking the heat on and cranking the thermostat up to 85, we've just thrown on our sweatshirts and curled up under our favorite throws, which saves quite a bit of money and energy. It's been easy because we own about four of Patagonia's Synchilla Blankets. (That's what happens when your parents live in Patagonia's hometown.) If, like us, you already have plenty of blankets, then you obviously don't need to buy any more. If you do need a couple, we can highly recommend these throws from Patagonia. They come in a variety of colors ($30) and prints ($40); they're warm; they're made from recycled materials, including soda bottles; and Patagonia pledges one percent of its sales (via 1% For The Planet) to environmental causes. Eventually, most of us will have to turn on the heat. When you do, here's a useful guide to efficiently setting your thermostat from the U.S. Department of Energy. Do you have any tricks for staying warm and keeping the thermostat down a little lower or off a little bit longer?
