rain quilting

I'm watching a video over on Stephanie Forsyth's Fiber Nation, in which she demonstrates free-motion stippling; and I immediately notice, since the volume is up, that the sewing machine makes a very comforting noise -- like rain falling, a sound we go without for months and months in MN. No wonder my son used to love being in the sewing room while I worked -- it's probably the warmest room in the house, and small, and that sound.... The "white noise" effect, so calming when is just a nice steady straight stitch.
