The thread guide keeps the thread running in the proper place. If the thread is not threaded correctly, the tension will be off, resulting in jammed or broken threads in the machine.On a sewing machine, the thread guide is a small part that is attached above the needle. It looks like a hook and it hold the thread in place as it is fed through the needle.
Another name that can be used for a single-strand wire is thread or strand.
The thread guide keeps the thread going straight in one direction.
The thread must come from the FRONT of the upright spool on the back of the machine. Thread through the small eyelet on the back (nearest the spool(s), projecting from the top), then through the thread guide at the front of the machine. If you are using a double needle (therefore two spools of thread), the thread from the left-hand spool should go through the top hole and the thread from the right-hand spool through the bottom hole. Come down to the tension disks. Bring the thread through the back disk, up again under the wire guide, and down under the thread guide that is just to the left of the tension disks. Bring the thread through the eye of the take-up lever (the piece that moves up and down when you sew) from RIGHT to LEFT. Guide the thread back down through the thread guide next to the tensioner. There is a little thread guide just inside the door on the left side of the machine; bring the thread through this guide. Then pull the thread through the wire guide above the needle (it's easiest to hold the thread horizontally to do this). Thread the needle front to back. HTH. YMMV.
The upper thread guide on a sewing machine is the markings on a sewing machine which show you how to thread the machine. It's usually indicated with arrows, dashes, and numbers, giving you step by step guides to thread the sewing machine properly.
The word thread has several other names. It is also known as fiber, strand, filament, fibril, gossamer, and even lisle.
