Steps written out by Crafting Step by Step from Jann Newton 's video (opens YouTube) (4:27). Published .

Also in:Crafts

The first time you thread a sewing machine, the path looks like a maze. Wires, slots, levers, a take-up arm that moves on its own. Miss one guide and the machine stitches loose loops or jams the needle.

Jann Newton from Newton Custom Interiors walks through it on a Singer Heavy Duty in this video, top thread and bobbin both.

Putting thread in a sewing machine is one continuous route with six or seven contact points. Miss the tension disks and it still runs, which is why the fault is so hard to spot. New to the machine? How to use a sewing machine covers the controls, hemming pants is the natural first project, and sewing a button by hand or sewing by hand covers what needs no machine at all.

What you need

  • Your machine and its manual, or the diagram on the body
  • All-purpose polyester thread
  • A bobbin that fits your machine. Bobbins are not universal
  • Scissors, and tweezers if the needle eye fights you

Threading a Singer or Brother sewing machine

Singer and Brother are the names people search by, and the top thread path is close to identical on both, and on Kenmore and Janome. Spool pin, upper guide, down the right-hand slot, U-turn at the bottom, back up the left slot, into the take-up lever, down the needle bar guide, through the eye front to back.

Almost every machine has that route printed on its body, numbered 1 through 6 or 7. Follow your machine's numbers ahead of any video, this one included. Two things change model to model:

  • The take-up lever. Some stand in the open so you hook the thread over. Others sit behind a slotted guard, and you push the thread in until it snaps.
  • The bobbin. Drop-in from the top, or front-load in a case behind a door. Not a brand split - Singer and Brother sell both.

Winding and putting in the bobbin

The bobbin carries the underside of every stitch, so it has to be wound and seated before the top thread does anything. Run thread through the small winder guide, wrap it round the empty bobbin a few turns, push bobbin and spindle right until they click, then run the pedal. Our bobbin winding guide covers that half.

A drop-in bobbin sits under the clear cover, unwinding the way the diagram beside the opening shows. A front-load goes into a metal case: through the slit in the rim, under the flat tension spring until you feel it grip, then back on its post, latch in the notch.

Threading the needle

By hand, snip the end fresh at an angle, keep the tail short, and push it through the eye front to back. A white scrap of paper behind the needle makes the eye much easier to see.

The automatic threader is the part beginners break. Needle at its highest point, presser foot down, then lower the threader slowly and let the hook swing through the eye. Lay the thread across the guide and release. Force the lever at the wrong needle height and the hook bends, and a bent one never catches the eye.

When the stitches go wrong

A nest of thread under the fabric looks like a bobbin fault and almost never is. Loops underneath mean the top thread is not seated between the tension disks. Raise the presser foot and rethread from the spool down. Raising the foot opens the disks so the thread drops between them instead of riding over the outside, which is why a machine threaded with the foot down still nests.

  • Skipped stitches. Usually the needle - blunt, bent, in backwards, or wrong for the fabric.
  • Thread snapping. Caught under the spool cap, tension too high, or old brittle thread.
  • Bobbin thread will not come up. The bobbin is in backwards. Reseat it the way the diagram shows.
  • Bobbin thread showing on top. Top tension is too tight. Drop the dial a number at a time.

Quick answer

Thread your sewing machine the right way in 7 clear steps. An easy project: about 10 minutes. You need 4 things, including Sewing Thread, Sewing Machine and Bobbin. The 7 steps start with set the spool on the spindle, run the thread through the upper guides, drop the thread through the tension disks, hook the thread into the take-up lever, guide the thread down to the needle bar and thread the needle front to back.

Step-by-step guide

7 steps, about 4 minutes. Tap a picture to jump to that step. Your progress saves automatically.

Tick each step off as you go.

  1. Step 1: Set the spool on the spindle

    Watch this step · 0:30

    Drop the spool onto the top spindle. Push the cap on so the thread feeds off in the direction your manual specifies. Most machines pull the thread from over the top of the spool, but some pull from underneath, so check before you start.

    Don't ram the cap down. The spool should turn freely as you pull thread off it.

    Tip:

    Smaller spools sit better when you flip the cap to its narrow side. That keeps the thread from slipping off the top.

    Back to all steps

  2. Step 2: Run the thread through the upper guides

    Watch this step · 1:05

    Pull a foot or two of thread off the spool and feed it through the metal guide on top of the machine. Most machines mark this as point one on the diagram. Then pass it through the second guide.

    The thread should sit flat in each slot, not bunched up. If it pops back out, push it in again until it stays.

    Back to all steps

  3. Step 3: Drop the thread through the tension disks

    Watch this step · 1:15

    From the top guide, pull the thread down the slot on the front of the machine. At the bottom, make a U-turn and bring the thread back up the second slot.

    You won't see anything happen, but the thread is now sandwiched between the tension disks tucked inside the body. Those disks pinch the thread just enough to keep your stitches even.

    Tip:

    Thread with the presser foot lever UP. Raising the foot opens the tension disks so the thread can drop down between them. With the foot down the disks are shut, the thread rides on top of them, and your top tension does nothing - that is where a nest of loops under the fabric comes from.

    Back to all steps

  4. Step 4: Hook the thread into the take-up lever

    Watch this step · 1:35

    Once the thread comes back up to the top, look for the take-up lever. It's the metal arm with a slot at one end that bobs up and down while the machine sews.

    Bring the thread to the lever and pull right to left. Use both hands and tug firmly until the thread snaps into the slot at the front of the lever.

    Tip:

    Turn the handwheel toward you to bring the take-up lever to its highest point before threading. It's much easier to reach the slot when the lever is up.

    Back to all steps

  5. Step 5: Guide the thread down to the needle bar

    Watch this step · 1:55

    Bring the thread back down the front of the machine. Just above the needle there's a small wire guide hooked onto the needle bar. Tuck the thread behind it.

    This last guide is what keeps the thread aligned with the needle eye when the bar moves up and down. Skip it and the thread slips sideways and breaks.

    Back to all steps

  6. Step 6: Thread the needle front to back

    Watch this step · 2:22

    Push the thread through the needle eye from the front of the machine toward the back. Keep the tail short and snip it cleanly with scissors so the end isn't frayed.

    Hold the tail with one hand once it's through and pull a few inches out so the thread doesn't pop back when you start sewing. Some days the eye threads on the first try. Other days it takes five.

    Tip:

    If you can't get the thread through, a pair of tweezers helps you grip the tail right at the eye. A self-threading needle or threader tool also makes this nearly automatic.

    Back to all steps

  7. Step 7: Bring the bobbin thread up through the plate

    Watch this step · 3:20

    With the bobbin loaded in its case, hold the needle thread loosely with your left hand. Turn the handwheel toward you a full rotation. The needle dips down, hooks the bobbin thread, and pulls a loop back up through the hole in the needle plate.

    Catch that loop with your fingers and pull until the bobbin tail comes free. Lay both threads toward the back of the machine and snap the bobbin cover on. You're ready to sew.

    Tip:

    If the loop won't come up, your bobbin might be sitting backwards. Pop the cover off and check that the thread feeds in the direction shown on the bobbin case.

Which direction do most sewing machines pull thread off the spool?

Quick reference

Key takeaways from How to Thread a Sewing Machine

5 questions, answers, and one-line explanations. Tap to expand.

  1. 1.Which direction do most sewing machines pull thread off the spool?

    Answer: From over the top - check your manual to confirm

    Most machines pull from over the top; check your manual since some pull from underneath.

  2. 2.What happens at the tension disks (the front slots)?

    Answer: The thread is sandwiched between disks that pinch it just enough to keep stitches even

    Hidden disks pinch the thread; they're what keep stitch tension consistent.

  3. 3.What is the 'take-up lever'?

    Answer: The metal arm with a slot that bobs up and down while the machine sews

    Take-up lever bobs up and down - thread snaps into its slot during threading.

  4. 4.Which direction do you push thread through the NEEDLE EYE?

    Answer: From front to back (toward the back of the machine)

    Front to back through the eye - keep the tail short and snip cleanly.

  5. 5.How do you bring the BOBBIN thread up through the needle plate?

    Answer: Hold the needle thread loosely, turn the handwheel toward you a full rotation, and catch the loop that comes through the plate

    One full handwheel rotation pulls the bobbin thread up as a loop; catch and pull it free.
