Today's a good one to do a draft audit in your home. Hold a lit candle next to shut windows and doors to see if it flickers. Since 20 percent of heat lost from the average home escapes from unsealed gaps, it pays to plug up annoying drafts. Use caulk, rope caulk, weather stripping, and door sweeps to keep drafts to a minimum. Remember to also fill in gaps between baseboards and the floor.
