Left to right ?? I don't recall any vintage Singer that threads
that way. right to left or from the front.----be sure your bobbin is threaded the right way also. do you have a manual. (that is probably answered elsewhere--I should read all of the answers before I jump in !) and check to see if
you threaded the top thread right.
