So the outcome of my dilemma was to open up all my windows to let the fresh air in. Of course, this causes me to notice all the grime that has built up in the window sills over the winter, so now I'm drawn to clean them. It takes me a whole day (inside with windows open) doing my spring cleaning. I should have set that machine up under the shade tree with the leaves and bugs. At least I would have worked a little on my quilt, which is not really work! Oh well, tomorrow it's supposed to rain.
