Small luxuries are sometimes necessary to combat the inevitable wintertime blues. Recently, I turned to silk pillows for a little pampering. A silly indulgence, I thought to myself -- until that first night when I fell asleep in a blissful silk cocoon. That dreamy sleep would have been enough to push chilly-weather doldrums aside, but it was waking the following morning that made me a convert. No static, no frizz, no creases etched into my cheeks -- something magic was clearly at work. After a week, I'd tossed my morning makeup routine and my bottle of hair serum. I also ordered a second set of silk shams, realizing it would be very hard indeed to go back to cotton pillowcases.
