Hi there,

Usually, the thread follows this general pattern: "left, down, up, down, into a hook, through the needle." Another way to know how to thread the machine is "Spool pin, tension, take-up lever, needle, using thread guides provided between these parts". The spool pin holds the spool of thread; the tension controls how easily the thread is pulled off the spool; the take-up lever takes the extra length of thread, that was needed to loop the upper thread around the bobbin case, back up, preparatory to making the next stitch.
The needle might be threaded from the left, the right, or from front to back. If it is already threaded, that is a clue to the direction; if not, the last thread guide before the needle, is located nearest to the direction from which you must thread the needle.

Thanks
