Here is a clear, step‑by‑step guide on how to thread a Singer Simple sewing machine , written so you can follow along right at your machine. (General Singer threading principles are consistent across the Simple line, even if small details vary by model.)

Before you start

  • Turn the machine off and unplug if you’ll have your hands near the needle.
  • Raise the presser foot so the tension discs open and the thread can seat correctly.
  • Turn the handwheel toward you until the needle and take‑up lever are at their highest point.

1. Set up the top thread

  1. Place your spool of thread on the spool pin on top of the machine, with a spool cap if your model came with one.
  1. Pull the thread from the spool and snap it into the first top thread guide near the spool pin (there’s usually a diagram with arrows printed on the machine).
  1. Follow the printed arrows, bringing the thread down the right‑hand groove on the front of the machine toward the tension area.

2. Through tension and take‑up lever

  1. Pull the thread between the tension discs; you should feel it slip into place, not ride on top.
  1. Continue down and around the bottom “U‑turn” channel, then up the left‑hand groove to the take‑up lever.
  1. Thread the take‑up lever from right to left through its eye, then pull the thread back down toward the needle area, following any small hooks or guides on the way.

3. Thread the needle

  1. Pass the thread behind the last guide located just above the needle clamp.
  1. Thread the needle front to back (or use the built‑in needle threader if your Simple model has one, following its printed icon).
  1. Pull a 6–8 inch tail of thread under the presser foot toward the back of the machine so it doesn’t pull out when you start sewing.

4. Insert and thread the bobbin

Many Singer Simple machines use a front‑loading bobbin case, but some are top‑drop‑in; check your front cover or top plate.

For a front‑loader (common on Simple models):

  1. Open the bobbin compartment and remove the bobbin case.
  1. Place the wound bobbin in the case so the thread forms a “P” shape as it comes off (it should pull in the direction shown in the diagram inside the compartment).
  1. Pull the thread into the bobbin case slot and under the tension spring so it flows smoothly.
  1. Insert the case back into the machine until it clicks and close the cover.

For a top‑drop‑in:

  1. Lift the clear bobbin cover plate, drop the bobbin into the compartment, and follow the arrowed path in the plastic plate.
  1. Pull the thread into the bobbin tension slot and out toward the back.

5. Bring up the bobbin thread

  1. Hold the top thread tail in your left hand.
  1. Turn the handwheel toward you one full turn so the needle goes down and back up, catching the bobbin thread.
  1. A small loop of bobbin thread will appear; pull the top thread gently to bring it fully through the needle plate.
  1. Arrange both threads under the presser foot and to the back, ready to sew.

Quick “why it matters”

  • Correct threading prevents loops, bird‑nesting under the fabric, and broken thread.
  • If stitches look uneven or the thread keeps snapping, the first fix is almost always: re‑thread the top and bobbin with the presser foot up.

If your stitches still look wrong

  • Re‑thread completely, making sure the presser foot is up while threading.
  • Check that the bobbin is turning in the direction shown in the diagram inside the bobbin area.
  • Use the correct needle size and a fresh needle if the thread is shredding.

TL;DR: Follow the arrows down–around–up–down for the top thread, thread the needle front to back, install the bobbin in the direction shown, then use the handwheel to pull the bobbin thread up before sewing.
