How to Thread a Sewing Machine: A Step-by-Step Guide for Beginners

This post may contain affiliate links. I only recommend products I actually use.

The first time I threaded my sewing machine, it took me about twenty minutes, two YouTube videos, and one moment where I genuinely considered returning the machine. The second time took five minutes. By the tenth time, I wasn’t thinking about it at all — my hands just knew where to go.

Threading a sewing machine is one of those things that feels impossibly fiddly until it doesn’t. Once it clicks, it really clicks. This guide is going to walk you through every step, explain what each part actually does, and cover the mistakes that trip up most beginners. By the end of this, you’ll have everything you need to thread your machine confidently and get stitching.

Before we dive in, one important note: every sewing machine is slightly different. The steps below follow the standard threading path that applies to most modern home machines — Brother, Singer, Janome, and similar brands all use the same general sequence. Your machine almost certainly has numbered guides or printed arrows on the body that show you the path, and your manual will have a diagram specific to your model. Use this guide alongside those resources, not instead of them.

What You’ll Need

Just two things: a spool of thread and a wound bobbin. If your bobbin isn’t wound yet, I’ll cover that first. If you’ve already got a wound bobbin ready to go, skip ahead to the upper threading section.

Step One: Wind Your Bobbin

The bobbin is the small spool that sits underneath your needle plate and supplies the lower thread. Without it, your machine can’t form a stitch — it takes two threads working together, one from above and one from below, looping around each other to create each stitch.

Most machines have a built-in bobbin winder on the top right of the machine. Here’s how to use it.

Place your spool of thread on the spool pin — the upright or horizontal pin at the top of your machine. If your machine came with a spool cap, place it over the end of the spool to keep it from spinning off.

Pull the thread across the top of the machine and wrap it around the bobbin winding pre-tension disc. This small disc is usually located near the top of the machine, and your machine’s diagram will show you exactly where. Threading around this disc matters — it controls the tension as the bobbin winds and without it, your bobbin will wind unevenly.

Place an empty bobbin on the bobbin winder spindle and wind the thread around the center hub of the bobbin a few times by hand to anchor it.

Slide the bobbin spindle to the right to engage the winder, then press the foot pedal. The machine will start winding. Let it run until the bobbin is full and the machine automatically slows or stops.

Snip the thread, slide the bobbin back to the left to disengage the winder, and remove it from the spindle. You’re ready for the next step.

Step Two: Load the Bobbin

Before you load the bobbin, raise your needle to its highest position by turning the handwheel toward you (always toward you — turning it away can cause threading issues). Raise your presser foot using the lever at the back right of the machine.

Open the bobbin compartment. On most machines this is a small sliding cover on the flat bed of the machine, directly in front of the needle. On front-loading machines it’s a door on the front of the machine, just below the needle. Check your manual if you’re not sure which type you have.

Drop your wound bobbin into the compartment. The direction matters. Most machines have a small arrow or diagram showing which way the thread should unspool — on the majority of modern machines, the thread unspools counterclockwise when you look down at it. Pull the thread through the slot in the bobbin case, following the guides marked on your machine, and leave a few inches of thread hanging free.

Close the bobbin cover and set the bobbin thread aside — you’ll bring it up later.

Step Three: Place the Spool and Begin Upper Threading

Place your spool of thread on the spool pin. If your machine has both a horizontal and vertical spool pin, check your manual for which one to use with your type of thread spool — parallel-wound spools (the ones where thread wraps parallel to the spool) work best on horizontal pins, cross-wound spools (where thread winds at an angle) work better on vertical pins. If in doubt, use the vertical pin.

Attach the spool cap to secure the spool, then follow the numbered path on your machine from top to bottom. Here’s the sequence on most machines.

Step Four: Follow the Thread Path

Pull the thread to the left and through the first thread guide at the top of the machine. This is usually a small hook or wire loop that directs the thread downward. You should feel a slight snap as the thread seats itself.

Bring the thread down through the right-hand channel toward the bottom of the machine. Most machines have a U-shaped channel built into the front body of the machine — your thread travels down the right side of this U.

At the bottom of the channel, pull the thread around through the tension discs. These are the two metal discs that press against each other and control how much resistance your thread experiences as it feeds through. Getting the thread between these discs is important — if you miss them, your upper tension won’t work at all and your stitches will look loopy and loose. One way to make sure the thread seats properly between the discs: always have your presser foot raised when threading. When the presser foot is up, the tension discs are open and the thread can slide in. When the presser foot is down, they’re closed. Threading with the presser foot down is one of the most common mistakes beginners make.

Bring the thread back up through the left-hand channel. At the top you’ll find the take-up lever — a hook or eyelet that moves up and down with the needle. Thread the take-up lever from right to left. This is a critical step. If your thread isn’t through the take-up lever, your upper thread will pull out of the needle within a stitch or two every single time you start sewing, and you’ll spend the next ten minutes wondering what you’re doing wrong.

Bring the thread back down toward the needle, following any additional guides on the lower part of the machine. Most machines have one or two small wire guides just above the needle that the thread passes through.

Step Five: Thread the Needle

Thread the needle from front to back — meaning the thread passes through the eye of the needle toward the back of the machine, not from the side. Some older manuals say to thread from left to right, but front to back is standard on most modern machines. Check your manual if you’re unsure.

If you’re struggling to see the eye of the needle, better lighting makes a world of difference. I keep a small LED task light at my machine for exactly this reason — it sounds minor until you’ve squinted at a needle eye for three minutes. A needle threader tool also helps, or use the built-in needle threader if your machine has one. To use a built-in threader, lower the threader hook through the needle eye, place your thread into the hook, and raise it back through. It takes a little practice but becomes fast once you get the hang of it.

Leave about six inches of thread pulled through the needle and set it aside.

Step Six: Bring Up the Bobbin Thread

Now you need to bring the bobbin thread up through the needle plate to join the upper thread. Here’s how.

Hold the upper thread loosely in your left hand — just a light grip, don’t pull it tight. Turn the handwheel toward you slowly to lower the needle down through the needle plate and back up again. As the needle comes back up, watch for a loop of thread being pulled up through the needle plate opening. That loop is your bobbin thread being caught by the upper thread.

Use a seam ripper, a pin, or your finger to pull that loop up through the hole until you have a free end of bobbin thread above the plate.

Pull both threads — upper and bobbin — out toward the back or side of the machine, leaving about six inches of both. This tail of thread is what feeds into your first stitches when you start sewing. If these threads are too short, they’ll pull out of the needle immediately when you start; if they’re too long, they can bunch up and jam underneath your first seam.

Step Seven: Test Before You Sew

Before you start your project, always test your threading on a scrap piece of fabric. Sew a few inches and look at both sides of the fabric. On a correctly threaded machine, the stitches should look identical on both sides — balanced little interlocking loops with no thread pulling to one side.

If you see loops of upper thread on the bottom of the fabric, your upper tension is too loose or your upper thread isn’t seated in the tension discs. Re-thread the upper path completely with the presser foot raised.

If you see loops of bobbin thread on the top of the fabric, your bobbin isn’t threaded correctly or your upper tension is too tight. Remove and reload the bobbin, making sure the thread follows the correct path through the bobbin case guides.

If your thread keeps pulling out of the needle after a stitch or two, check that your thread is through the take-up lever — that’s almost always the culprit.

Common Threading Mistakes and How to Fix Them

Threading with the presser foot down is probably the most common one. It looks like everything is threaded correctly but the tension discs are closed, so the thread isn’t actually seated between them. Always raise the presser foot before you thread.

Missing the take-up lever is the second most common. If the thread keeps pulling out of your needle the moment you start sewing, go back and make sure the thread is through that lever.

Loading the bobbin in the wrong direction causes consistent tension problems that are hard to diagnose because everything looks fine from the outside. If your stitches are uneven or loose on the bottom and you’ve already checked the upper threading, flip your bobbin and try again.

Not leaving enough thread tail after threading causes the thread to pull out before your first stitch forms. Six inches is a good rule of thumb.

One Last Thing

The numbered guides printed on your machine body are there for a reason — follow them in order, every time. When threading becomes second nature, you’ll probably stop thinking about the numbers. But while you’re learning, those guides are your map. They’ve saved me more times than I’d like to admit.

Threading your machine correctly is the foundation of everything else. Tension problems, skipped stitches, thread breakage, uneven seams — a surprising number of those issues trace back to a threading mistake. Get this right and a lot of other problems take care of themselves.
