Love your table runner, you have done a beautiful job, just do the same with your first quilt.. I too have a 1976 singer slant needle/self winding bobbin,have sewed a million + stitches on it, have all but retired it. Have a singer quantum 500 that I use most of the time. then just purchased a new Long arm, having lots of fun learning how to quilt on it.
Happy quilting.
