"Summer-ize your fireplace."

After we clean our fireplace each spring, my partner, Hermes, and I put in white birch logs. They're an easy way to lighten up an otherwise wintry part of the room. We use this trick in clients' spaces, too: I scouted the woods around my house for months to find a downed birch big enough to use in the fireplace at the New York Public Library.
