Hello from West Virginia! I also love old sewing machines. Not sure when they become antique. I sew all my quilts on old Singers. I'm currently using my 401, getting ready to switch to the 500 (Rocketeer), and then the Featherweight 221. I go back and forth after a couple of months. I have a Singer Treadle, and used it when I sewed some polyester quilts together a few years back. These machines sure are workhorses!
