I love the chalk drawing on one of the cabinet parts. The old Singer treadle that I have (and have never done anything with it yet) has a tic-tac-toe scratched in (probably with one of Mom's pins) on the back of the machine. Kiddo was probably standing at the back of the machine with a sibling or friend while Mom did her sewing. My DH told me that he and his brother took turns manning the treadle while his mom sewed. I suppose that was her way of knowing where they were while she did her sewing.
