How To Tie The End Of A Thread After Sewing Securely

You have sewn a seam. You have made many stitches. What happens next? You must stop the thread. You must keep the stitches safe. How do you do this? You tie the end of the thread. This is very important. It stops your sewing from coming undone. This story tells you how to tie the end of a thread after sewing. It helps you secure sewing thread. It shows you how to make a good finishing sewing knot. You will learn about tying off stitches. You will see how to make a hand sewing knot at end. You will learn about machine sewing thread finish. You will know how to secure a seam end. This helps prevent thread unraveling sewing. We will talk about backstitching thread end and locking stitches sewing. You will learn how to fasten sewing thread end.

Why Keep Thread Safe?

You make something with sewing. Maybe it is a bag. Maybe it is a dress. You put time into it. You want it to last.
If the thread end is not safe, it can come undone. One stitch comes out. Then another. Soon, the whole seam might open up.
This makes your hard work break.
A safe thread end keeps everything together. It makes your sewing strong. It makes it last a long time. This is why securing sewing thread is key. It helps prevent thread unraveling sewing.

Seeing Hand Sewing Knots

When you sew by hand, you start with a knot. You also end with a knot. The knot at the end is very important. It holds the last stitches tight. It is how you make a hand sewing knot at end. This is part of tying off stitches. It makes a good finishing sewing knot.

There are different ways to make this last knot. Some are easy. Some are stronger. We will look at some ways.

Way 1: The Simple Loop Knot

This is often the first knot you learn. It is good for many things.
How to do it:

Sew your last stitch.
Do not pull the thread all the way through. Leave a small loop of thread.
Put your needle through this loop.
Pull the thread tight. A small knot forms right next to your fabric. This knot is near your last stitch.
You can make this knot again. This makes it stronger. Do the same steps. Make another loop. Push the needle through. Pull it tight. Do this maybe two or three times.
Cut the extra thread. Leave a little bit of thread after the knot. Do not cut too close.

This simple loop knot is quick. It works well for easy projects. It is a basic way of tying off stitches. It helps fasten sewing thread end.

Way 2: The Tailor’s Knot (or French Knot Finish)

This knot is a bit more safe. It sits right on the fabric.
How to do it:

Sew your last stitch.
Bring your needle up. The thread comes out of the fabric.
Hold the thread with one hand. Keep it a little loose.
Use your needle. Put the tip next to where the thread comes out.
Wrap the thread around the needle. Wrap it two or three times.
Keep holding the wrapped thread gently.
Push the needle back into the fabric. Push it in very close to where the thread first came out. Maybe just a tiny bit away.
Pull the needle and thread through slowly. Keep holding the wraps with your finger. Help the knot form.
As you pull, the wraps will slide down the needle. They will turn into a knot. This knot sits flat on the fabric surface.
Pull it all the way tight.
Make this knot one or two more times. Make each new knot right on top of the first one. This makes a strong bump of thread.
Cut the extra thread. Leave a small bit.

This knot is very secure. It is great for stitches that get pulled a lot. It is a strong finishing sewing knot for hand sewing. It truly helps in securing sewing thread.

Way 3: Knotting Into The Stitch Itself

This way hides the knot a little better. It ties the new knot around a stitch already made.
How to do it:

Sew your last stitch.
Put your needle under the last stitch you made. Or put it under a stitch nearby. The thread will go around that stitch.
Pull the thread mostly through. Leave a loop.
Put your needle through this loop.
Pull it tight. The knot forms around the stitch you went under.
Do this again. Go under the same stitch or a nearby one. Make another knot.
Make two or three knots like this. Make them close together.
Cut the extra thread.

This method is good for securing sewing thread when you do not want a knot bump right on top. It fastens sewing thread end neatly.

Way 4: Running Thread Inside The Seam

This method does not make a knot you can see easily. It hides the thread end inside the fabric layers. This is a nice way to finish sewing knot neatly.
How to do it:

Finish your sewing line.
Put your needle into the fabric layers. Push it between the two pieces of fabric. Go inside the seam area.
Push the needle along for about half an inch (about 1 cm). Keep it inside the fabric.
Bring the needle out.
Pull the thread gently. Do not pull the fabric tight.
Cut the thread right where it comes out of the fabric.
The thread end is now hidden inside the fabric. It is held safe by the fabric itself.

This is a very clean way to secure a seam end. It is good for fabrics that might show a knot bump. It helps prevent thread unraveling sewing without a hard knot.

Table: Hand Sewing End Knots

Here is a look at the different ways to tie off stitches by hand.

Knot Name	How It Looks	Strength	How Hard	Good For…	Hides End?
Simple Loop Knot	Small bump at the end	Good	Easy	Most projects, quick finish	No
Tailor’s Knot	Small, raised knot	Very Good	Medium	Areas with stress, strong hold	No
Knot Into Stitch	Knot hidden near stitch	Good	Medium	Hiding knot, flatter finish	Yes (partly)
Running Thread	No visible knot	Good	Easy	Clean finish, delicate fabrics	Yes

Seeing Machine Sewing Ends

Machine sewing is different. The machine makes stitches very fast. How do you make the end safe? You cannot tie a knot with a needle in the same way. Machine sewing thread finish uses other tricks. The main ways are backstitching thread end and locking stitches sewing. These help secure a seam end.

Way 1: Backstitching

This is the most common way to fasten sewing thread end with a machine. You sew a little bit backwards at the start and end of your seam.
How to do it:

Start sewing your seam. Sew forward for about half an inch (about 1 cm).
Stop. Do not lift the needle.
Press the reverse lever or button on your machine.
Sew backwards for about half an inch (about 1 cm). Sew right over the stitches you just made.
Stop.
Release the reverse lever.
Sew forward again. Sew all the way to the end of your seam.
When you reach the end of the seam, sew forward for about half an inch (about 1 cm) past where you want the seam to end.
Stop. Do not lift the needle.
Press the reverse lever again.
Sew backwards for about half an inch (about 1 cm). Sew over the stitches you just made. Sew back to the real end of the seam.
Stop. Release the lever.
Sew forward just two or three stitches. This brings the thread loop up nicely.
Lift the needle and presser foot. Pull your fabric out.
Cut the threads.

The many layers of stitches made by sewing back and forth lock the thread ends together. This backstitching thread end method is very strong. It is great for seams that will have a lot of pull. It is a standard machine sewing thread finish. It really helps in securing sewing thread on a machine. It is a simple way to how to secure a seam end.

Way 2: Locking Stitches

Some sewing machines have a special stitch button. It might be called a “lock stitch” or “reinforcement stitch”. This button tells the machine to make several very short stitches right on top of each other. This bunches the thread up tightly.
How to do it:

Sew your seam almost to the end.
When you are near the end, press the lock stitch button.
The machine will make a few tiny stitches in place. It stops.
Lift the needle and presser foot.
Pull your fabric out and cut the threads.

Or, some machines do this at the very start:

Put your fabric under the foot.
Press the lock stitch button before you start sewing forward.
The machine makes tiny stitches.
Then it is ready for you to sew your seam forward.

Locking stitches sewing is fast if your machine has the button. It makes a small, neat bunch of stitches. This also helps fasten sewing thread end and is a good machine sewing thread finish. It is another way of locking stitches sewing.

Way 3: Leaving Long Thread Tails

Sometimes, you sew to the end of a seam. You do not backstitch. This might be on purpose. Maybe you do not want the backstitch bulk. This happens in some types of sewing.
How to deal with the ends:

Sew your seam.
When you reach the end, lift the presser foot and pull the fabric out.
Cut the threads, but leave them long. Leave tails that are 4 to 6 inches (10-15 cm) long.
Pull the top thread end through to the back side of the fabric. Use a needle or pin to grab the loop.
Now you have both thread ends on the back side.
Tie these two threads together. Make a simple knot. Tie it close to the fabric.
Tie another knot. Make it a double knot.
Cut the extra thread tails. Leave a little bit after the knot.

This method takes more time than backstitching. But it is good when backstitching might look bad or make the seam too thick. It is a manual way to finish sewing knot after machine sewing. It helps fasten sewing thread end when you don’t backstitch. It is another way of securing sewing thread.

Way 4: Sewing Into the Seam Allowance

This is similar to the hand sewing method. You can do it with a machine too.
How to do it:

Sew your seam to the end.
Instead of stopping right away, turn your fabric slightly. Sew a few stitches just inside the seam allowance. The seam allowance is the fabric edge outside the stitch line.
Sew about half an inch (about 1 cm) into the seam allowance. Stitch close to the edge.
Cut your threads.

These stitches inside the seam allowance hold the main seam stitches safe. They are cut off later when you finish the seam allowance edge. This method is good for seams that will be finished later (like with an overlocker). It is another way to secure a seam end. It is a machine sewing thread finish method.

Table: Machine Sewing End Methods

Here are ways to fasten sewing thread end when using a machine.

Method Name	How It Looks	Strength	Speed	Good For…	Hides End?
Backstitching	Bunch of stitches on seam	Very Good	Very Fast	Most seams, strong hold	No
Locking Stitches	Tiny stitches in place	Good	Very Fast	Machines with the button, neat	No
Tying Long Tails	Hand-tied knot on back	Good	Slow	Where backstitch looks bad	Yes (on back)
Sewing in Seam Allow.	Stitches in edge fabric	Good	Fast	Seams with finishing edges	Yes (cut off later)

Getting Securing Sewing Thread Right

No matter if you hand sew or machine sew, making the end safe is important. It is about securing sewing thread. It stops all your work from coming undone. This prevents thread unraveling sewing.

Think about these things:

Where is the seam? Will it be pulled a lot? A seam on a bag strap needs a very strong end. A seam just for show might not need as much.
What fabric are you using? Thick fabric can hide knots. Thin fabric might show them. Slippery fabric needs extra care to keep knots from coming undone.
What thread are you using? Some threads are stronger than others. Some threads are more slippery. You might need more knots with slippery thread.
How does it need to look? Do you need a very clean finish? Or is a small knot okay?

Choosing the right way to tie off stitches depends on your project.

Learning How To Secure A Seam End Better

Here are some extra tips for securing sewing thread:

Use the right thread: Match your thread to your fabric and your project’s use. Stronger thread means a stronger seam end.
Use the right needle: A good needle helps make neat stitches. This makes tying off easier. A sharp hand needle helps get through fabric for knots. A machine needle that is right for the fabric helps make good stitches for backstitching.
Practice: Try different ways to tie off stitches on scrap fabric. See which one you like best. See which one looks best for your fabric.
Double or Triple Knots: For hand sewing, making more than one knot in the same spot adds strength. Don’t just make one knot. Make two or three. This makes a stronger finishing sewing knot.
Sew Over Ends: Sometimes, the next seam you sew can go over the end of the last one. This locks the first seam’s end in place. It is like using the next seam to secure the seam end of the first one. This is common in clothes making.
Use Fray Check: This is a liquid you can put on thread ends. It makes them hard. It stops them from coming apart. You can put a tiny drop on your knot after you make it. This adds extra safety to your fastening sewing thread end.

Making Sure It Stays Safe

You have tied your knot or backstitched. How do you know it will hold?

Give it a gentle pull: Pull on the seam area near the end. Does it feel solid? Does the end feel like it will stay put? If it feels loose, maybe you need to add another knot or backstitch more.
Check the knot size: For hand sewing, is the knot big enough? It should be bigger than the holes made by your needle. If it is too small, it can pull through.
Look at machine backstitches: Are the backstitches right on top of the original stitches? Are there enough of them (about half an inch)?
Trim ends carefully: When you cut the thread ends after securing them, do not cut too close to the knot or the fabric. Leave a small tail (maybe a quarter inch or half a cm). Cutting too close can make the knot come undone or the stitches loosen.

Taking these steps helps you check that your tying off stitches was done well. It means your securing sewing thread is finished right.

Getting Thread Ends Ready

Before you even start securing the thread end, make sure you have enough thread. Do not run out right at the end of a long seam! It is annoying. Leave enough thread to work with for making the knot or backstitching. For hand sewing, this might mean having 4-6 inches (10-15 cm) of thread left. For machine sewing, you need enough to sew back and forth and still have tails to cut.

Seeing Why Different Fabrics Matter

The fabric you sew on changes things.

Thick fabrics (like denim): These fabrics are strong. They can handle backstitching well. Hand sewing knots can be bigger and hide better.
Thin fabrics (like silk): Backstitching can look bulky. Tying long tails and knotting by hand on the back is often better. Running the thread inside the seam can be very clean. Knots need to be small but strong.
Stretchy fabrics (like jersey): These fabrics move. Your securing sewing thread needs to move too. A slightly looser knot (but still safe!) or using a stretch stitch on a machine can help. Backstitching with a regular stitch might break the thread when the fabric stretches. Some machines have a special “reinforcement” stitch that has stretch for seams.
Fuzzy fabrics (like fleece): These fabrics hide everything! Knots and backstitching can disappear. You still need to make them strong, even if you can’t see them well.

Knowing your fabric helps you choose the best way to fasten sewing thread end.

Finishing Sewing Knot Details

Let’s look closer at the hand sewing knots again.

The Simple Loop Knot Steps Again

Sew last stitch. Thread comes through fabric.
Put needle next to thread. Make thread loop with fingers.
Push needle through loop.
Pull thread tight. Knot forms near fabric.
Repeat 2-4 two more times in same spot.
Cut thread.

This is the simplest way of tying off stitches. It’s a quick finishing sewing knot.

The Tailor’s Knot Steps Again

Sew last stitch. Thread comes out of fabric.
Hold thread loose with one hand.
Put needle tip next to where thread comes out.
Wrap thread around needle 2 or 3 times.
Hold wraps gently with finger.
Push needle back into fabric very close to where thread came out.
Pull needle through slowly. Use finger to help knot slide down.
Pull thread tight. Knot sits on fabric.
Repeat 2-8 two more times in same spot.
Cut thread.

This gives a strong hand sewing knot at end. A very secure finishing sewing knot.

Knotting Into Stitch Steps Again

Sew last stitch.
Put needle under last stitch made (or one nearby).
Pull thread under stitch, leave loop.
Push needle through loop.
Pull tight. Knot forms around stitch.
Repeat 2-5 two more times under same stitch or nearby.
Cut thread.

This helps hide the knot while tying off stitches. Good for securing sewing thread subtly.

Seeing Machine Sewing Finishes Closer

Let’s look closer at the machine methods. These are all about machine sewing thread finish.

Backstitching Steps Again

Start seam. Sew forward ~1 cm.
Stop. Press reverse button.
Sew backward ~1 cm over first stitches.
Stop. Release reverse button.
Sew forward to end of seam.
Sew forward ~1 cm past end point.
Stop. Press reverse button.
Sew backward ~1 cm over stitches, back to end point.
Stop. Release reverse button.
Sew forward 2-3 stitches.
Lift foot, needle. Cut threads.

This is the standard way to fasten sewing thread end on a machine. A strong backstitching thread end makes a very secure seam end. It is key to locking stitches sewing on most machines.

Locking Stitches Steps Again (Machine Button)

Sew seam to almost the end.
Press “lock stitch” or “reinforce” button.
Machine makes tiny stitches in place.
Machine stops.
Lift foot, needle. Cut threads.

Or:

Put fabric under foot.
Press “lock stitch” button.
Machine makes tiny stitches.
Start sewing seam forward.
Sew to end. Cut threads (some machines do auto-cut after this).

This is a fast way of locking stitches sewing if your machine has the feature.

Tying Long Tails Steps Again (Manual Machine End Secure)

Sew seam to end.
Lift foot, pull fabric out. Leave long thread tails (~10-15 cm).
Find top thread loop on bottom. Pull it through to back with needle.
Now both tails are on the back.
Tie tails together close to fabric. Simple knot.
Tie a second knot (double knot).
Cut threads, leave small tails (~0.5 cm).

This is a manual way to create a finishing sewing knot after using the machine. It helps secure a seam end when backstitching is not wanted.

Sewing Into Seam Allowance Steps Again

Sew seam to end.
Turn fabric slightly.
Sew forward a few stitches (~1 cm) just inside the seam allowance (the extra fabric outside the seam line).
Cut threads.

This secures the end stitches by sewing them into the part of the fabric that will be finished or cut away later. It helps secure a seam end neatly.

Seeing How To Prevent Thread Unraveling Sewing

All these methods share one main goal: to prevent thread unraveling sewing. The thread wants to pull free. The knot or the backstitches stop it.
Think of it like a little anchor. The end of the thread is the rope. The knot or backstitch is the anchor. It holds the rope tight so it cannot pull back through the fabric holes.

Choosing the right anchor is important. A big ship needs a big anchor. A small boat needs a small one. A seam that will be pulled hard needs a very strong way to fasten sewing thread end. A seam that will just sit there needs less.

Learning About Locking Stitches Sewing More

The idea of “locking stitches” is key. Whether you use a machine’s lock stitch feature or backstitch, you are locking the threads. You are making it so the stitch cannot come undone easily.
With hand sewing, the knots lock the thread. They make a bump the thread cannot pull through.
With machine sewing, backstitches make a pile of thread. This thread bulk locks the last stitches in place. The lock stitch feature does the same thing in a smaller space.

Both hand and machine methods are ways of locking stitches sewing to finish the job right.

FAQ – Questions People Ask

Q: Can I just tie a knot at the very start and end of machine sewing without backstitching?
A: You can leave long tails and tie them by hand on the back. This is method 3 for machine sewing. But just cutting the threads without any securing means the seam will likely come undone very fast. Backstitching or tying off by hand is needed to secure a seam end.

Q: My machine backstitch looks messy. What can I do?
A: Practice helps. Make sure your thread is right for the fabric. Sometimes, sewing just a few stitches forward at the very end after backstitching (method 1, step 10) helps make the cut point cleaner. Or, use the long tails method and tie by hand. This is a different machine sewing thread finish.

Q: When hand sewing, how many knots do I need at the end?
A: It is best to make two or three knots right on top of each other. One knot might not be strong enough, especially on slippery fabric or if the knot is small. Making multiple knots makes a stronger finishing sewing knot. This is key to a good hand sewing knot at end.

Q: Does securing the thread end matter for temporary stitches?
A: For temporary stitches (like basting), you might not need a super strong end. A single knot or no knot at all might be fine, since you will take the stitches out later. But for any stitch meant to stay, you must fasten sewing thread end properly.

Q: My thread keeps coming undone even after tying a knot. Why?
A: Maybe your knot is too small for the needle hole. Maybe your thread is very slippery (like silk or some polyesters) and the knot is not holding. Try making more knots (3 or 4). Try a different knot (like the tailor’s knot for hand sewing). Use Fray Check. Make sure your knot is pulled very tight. Or, for machine sewing, make sure your backstitch is long enough (about 1 cm). This is a problem with prevent thread unraveling sewing. Stronger securing sewing thread steps are needed.

Q: How close should I cut the thread to the knot or fabric?
A: Do not cut right next to it. Leave a small tail, about a quarter inch (0.5 cm) to half an inch (1 cm). If you cut too close, the end can wiggle free and pull the knot undone.

Closing Thoughts

Making your sewing projects strong means paying attention to the small things. Tying off stitches correctly is one of those small things that makes a big difference. Whether you are using a hand sewing knot at end or a machine sewing thread finish like backstitching thread end, the goal is the same: prevent thread unraveling sewing. Learning how to secure a seam end well means your stitches will stay put. Your hard work will last. You will have safe seams because you know how to properly fasten sewing thread end. It takes a little extra time at the end of your sewing line, but it is time well spent for securing sewing thread.
