Sorry for the late post; I'm really sick and had family in town this weekend. What have you all been up to?
Despite the nagging cough, fever, and sniffles, I have double/tripled paned some back windows with plastic, and laid plans for sealing around the windows on the exterior, thanks to your wonderful suggestions about foam and caulk. I'm also gathering fabric for thick curtains and window insulators, and digging out the old draft dodgers. I've also dusted off the programmable thermostat we installed a few years ago, and made sure that the batteries were fresh, and that the program was sufficient for this year's schedule.
