Thank you to whoever it was who mentioned using masking tape on windows when you're desperate to stop airflow. Our house was built in 1948 - still has the original windows, and we haven't lived here long enough yet to replace them. Well, the weather in New Hampshire today sure showed me which windows are the priority to be changed out next summer. The cold air screaming into the house was outrageous. Then I remembered someone mentioning this down and dirty fix a while back. It ain't pretty, but durned if it ain't effective. My house is not freezing, and my fingers are not numb at the keyboard anymore. The wood stove seems happier too. Thanks!
