(Next time I will use matching thread!) One of the great joys in my life is the womblike comfort of "Smart Wool" socks. Unfortunately, they wear out under the heel and get discarded. Today, as I found another hole and contemplated the loss of a cozy friend, I remembered that my long-neglected sewing machine had a darning stitch. I delighted in hearing the smooth, quiet operation of my long-neglected Pfaff as it put this sock back into working condition and thought, "Today, I will feel just a little bit less guilty about neglected socks and an unused sewing machine".
