Joanne, thanks for mentioning using comforters! My Dad called yesterday, asking if I had any ideas for keeping his greenhouse warmer at night. He still hasn't run electricity to it for the heater. It's been much hotter than he wants it to be during the day, and it's much colder than he wants it at night. He finally got out there and opened the door and windows, and it cooled off, but needs something to keep it warm at night. I'll let him know about this, as it's a perfect solution for him!
