That reminded me of an image I had seen on The Selvage Blog. She is always sharing interesting things. On the side of her blog she has linked to another blog that has this animated gif that shows how a sewing machine actually works.
It is mesmerizing watching the needle go up and down, up and down, sewing, sewing, sewing. . . . About the same feeling I get as I am sewing -- except not quite as satisfying because I have nothing to show for it.
Hope your Friday is full of fabric!
