Secrets Revealed: How To Finish A Sewing Knot Strong

How do you tie off sewing thread so your stitches stay put? Learning how to finish a sewing knot or secure the end of your thread is key to making sure your sewing projects last. Good finishing stitches prevent sewing seam unraveling. This guide will show you easy ways to secure sewing stitches, covering both machine and hand sewing knot techniques. Let’s dive into how to tie off thread strongly every time.

Why Secure Your Stitches?

Think about your sewing project. It might be a piece of clothing, a bag, or a home decor item. These things get used, washed, and moved around. If your stitches are not secured properly at the start and end, they can easily come undone. This is often called unraveling. A seam that unravels can ruin the whole project. Using strong finishing stitches is like locking your work in place. It ensures your effort lasts and your sewing stays together. Knowing how to tie off sewing thread well is just as important as sewing the seam itself.

Securing Threads When Machine Sewing

Machine sewing is fast and strong, but you still need to secure the ends of your seams. Most sewing machines have built-in ways to help you do this. The most common method is backstitching. Another way is using a special lock stitch if your machine has one.

Mastering the Backstitch

Backstitching is the most basic way to secure a seam end on a machine. It involves sewing backward over the last few stitches you made. This creates a small, strong bundle of stitches that act like a knot.

How to Backstitch:

1. Sew your seam: Sew your seam line like you normally would.
2. Reach the end: When you get to the very end of your seam, stop.
3. Go backward: Most machines have a reverse lever or button. Hold or press this button and sew backward over the last 3-5 stitches.
4. Go forward again: Release the reverse button and sew forward again over the same stitches. This creates a strong bar of stitches.
5. Cut threads: Lift the presser foot and needle, then pull your fabric out. Cut the threads close to the fabric.

This simple backstitch at end of seam method creates locking stitches that prevent the thread from pulling out. You also backstitch at the start of your seam for the same reason.

When to Use Backstitching

• Starting and ending most straight seams.
• Securing stitches on stress points, like corners or where straps attach.
• Anywhere you need to prevent sewing seam unraveling quickly and easily.

Variations of Backstitching

Sometimes a full backstitch isn’t neat enough, especially on visible seams or lighter fabrics.

• Tiny Backstitch: Instead of 3-5 full stitches backward, just backstitch 1-2 stitches. Then sew forward 1-2 stitches. It’s less bulky but still secures the end.
• Sewing in Place (Lock Stitch Function): Some machines have a ‘lock stitch’ button. When pressed at the end of a seam, the machine sews several tiny stitches right in one spot. This creates a neat knot effect without bulky backstitching. It’s very effective for securing thread ends neatly. This function creates true locking stitches.

Securing Thread Tails After Machine Sewing

Even with backstitching or a lock stitch, you’ll have thread tails. For extra security, or if you forgot to backstitch, you can secure these tails.

Methods for Thread Tails:

• Tie a Knot by Hand: Thread the tails onto a hand sewing needle. Pass the needle through the last few stitches on the back side of the fabric. This hides the tails. Then, make a small knot close to the fabric. Cut the thread.
• Use Fabric Glue ( sparingly!): A tiny dot of fabric glue on the back of the last stitch can hold the thread end. This is not for all fabrics or projects and should be used with care.
• Sew Tails into Seam Allowance: If you have a seam allowance, you can thread the tails onto a needle and run them through the seam allowance fabric for an inch or two. This hides and secures them.

Knowing these machine sewing knot techniques and finishing stitches helps ensure your seams are strong and durable. The goal is always to secure the thread end so it cannot pull free.

Securing Threads When Hand Sewing

Hand sewing requires different finishing stitches than machine sewing. Since you are the ‘machine,’ you control every stitch and knot. A well-made hand sewing knot is essential to start and end your seams strongly. Learning how to tie off sewing thread by hand is a core skill.

Starting with a Knot

Before you even start sewing by hand, you need to make a knot at the end of your thread. This knot catches on the fabric and holds your first stitch.

Basic Hand Sewing Knot (Away Knot):

1. Cut your thread. Don’t make it too long, or it might tangle. About 18-24 inches is good for most jobs.
2. Thread your needle.
3. Hold the end of the thread between your thumb and forefinger.
4. Wrap the thread end around your fingertip once or twice.
5. Roll the thread off your fingertip using your thumb. The wrapped thread will form a loop.
6. Pull the needle and thread through the loop you made, pulling it tight to form a knot at the very end of the thread.
7. Trim any excess thread tail close to the knot.

This basic hand sewing knot is simple and effective for starting most seams.

Ending a Hand Sewn Seam

Finishing a hand-sewn seam is crucial. You need to secure the thread end so your stitches don’t pull out. This is where proper finishing stitches come in.

Method 1: The Simple Knot at the End

This is the most common way to finish a hand seam.

1. Sew your last stitch and bring the needle and thread through to the back of the fabric.
2. Make a tiny stitch very close to where your thread came out. Don’t pull it tight yet.
3. Before pulling the stitch tight, pass the needle through the loop of thread you just made.
4. Pull the thread gently. A small knot will form right on the fabric surface near your last stitch.
5. Repeat step 2-4 one or two more times in the exact same spot. Making several knots on top of each other makes a stronger finish.
6. Cut the thread close to the knot.

This method is good for many uses, but the knot is visible on the fabric.

Method 2: The Hidden Knot

This method makes the knot less visible, often hiding it within the layers of fabric or the seam allowance.

1. Sew your last stitch and bring the needle and thread through to the back of the fabric.
2. Instead of knotting right on the surface, pass the needle under a few existing stitches on the back of the fabric. Sew through about 1/4 inch (0.5 cm) of fabric, staying very close to the seam line.
3. Pull the thread gently, but leave a small loop where the thread exits the fabric.
4. Pass the needle through this loop one or two times.
5. Pull the thread tight. A knot will form close to the fabric surface, often pulling slightly underneath the previous stitches, making it less visible.
6. For extra security, pass the needle under a few more stitches or through the fabric layers for a short distance (about an inch or two). Pull the thread through and cut it close to the fabric. The thread tail is hidden.

This hidden knot method is great for seams on clothing or anywhere you want a neat finish without a visible knot bump. It’s a very effective way to secure thread end in hand sewing.

Method 3: Reinforcing Stitches

Instead of (or in addition to) a knot, you can use several very short stitches sewn in the same place to secure the end. This creates a strong bar of thread like machine backstitching.

1. Sew your last stitch.
2. Make 3-4 tiny stitches (about 1/16 inch or 1-2 mm long) right on top of each other at the end of your seam. Keep these stitches very close to the seam line.
3. After the last tiny stitch, you can make a small knot close to the fabric if you like (using Method 1 or 2) for extra peace of mind.
4. Cut the thread.

This method creates strong locking stitches by hand. It’s often used alongside a small knot for maximum security, helping to prevent sewing seam unraveling.

Table of Hand Sewing Finish Methods

Method	Description	Visibility of Knot	Best For	Security
Simple Knot at the End	Knot made directly on the fabric surface after the last stitch, often repeated.	High	General sewing, repairs, quick finishes.	Good
Hidden Knot	Knot made within a loop after passing thread under existing stitches.	Low	Clothing seams, visible areas, neat finish.	Very Good
Reinforcing Stitches	Multiple small stitches sewn over the last stitch area.	Low	Stress points, heavy-use items, strong finish.	Excellent

These hand sewing knot techniques and finishing stitches give you several ways to secure your thread ends effectively. Choosing the right method depends on your project and where the seam is located.

Special Situations & Advanced Techniques

Sometimes you need more than the basic knot or backstitch. Certain projects or thread types call for specific sewing knot techniques.

Sewing Buttons

Securing the thread when sewing on a button is vital. You don’t want the button falling off!

1. Start with a knot on the back of the fabric (Away Knot or a small knot near the button position).
2. Sew through the button holes and fabric.
3. Finish on the back of the fabric. Make a small stitch right near the last stitch, pass the needle through the loop, and pull tight to make a knot. Repeat this knot 2-3 times in the same spot.
4. For extra security, especially on a button with a shank or where you created one: Wrap the thread tightly around the thread connecting the button to the fabric a few times. Then, pass the needle to the back of the fabric again. Make another small knot on the back fabric surface. Cut the thread.

This ensures your button is held on with secure sewing stitches.

Starting a New Thread Mid-Seam

If your thread breaks or runs out before you finish a seam, you need to add new thread cleanly and securely.

• Machine Sewing: Sew over the end of the old thread for about 1/2 inch (1 cm). Start your new thread about 1/2 inch (1 cm) before where the old thread ended. Sew forward over the old stitches, then continue the seam. This overlaps the stitches, securing both ends. You can even do a small backstitch at the start of the new thread for extra security.
• Hand Sewing: Bring the old thread to the back of the fabric. Secure it with a hidden knot or reinforcing stitches. Start your new thread about 1/2 inch (1 cm) before where the old thread ended. Secure the start of the new thread with an Away Knot hidden on the back. Sew forward, overlapping the last few stitches of the old thread.

Overlapping stitches is a key technique for securing thread ends when joining threads.

Using Thicker or Specialty Threads

Some threads (like topstitching thread or embroidery floss) are thicker. Knots made with these can be bulky.

• Machine: Thicker threads might need a longer backstitch (6-7 stitches) or the sewing-in-place lock stitch feature if your machine handles the thread well.
• Hand: For hand sewing knot techniques with thicker threads, the hidden knot is often better than a surface knot which would be very large. Reinforcing stitches are also excellent as they spread the bulk. You might need to pass the thread through the knot loop fewer times (once instead of twice) to avoid excessive bulk.

Adapting your finishing stitches based on thread type is important for both strength and appearance.

Common Mistakes to Avoid

Even experienced sewers sometimes make mistakes with finishing stitches. Here are some common ones and how to avoid them:

• Not Backstitching Enough (Machine): Just one or two stitches backward isn’t always enough, especially on fabrics that fray easily. Aim for 3-5 stitches.
• Backstitching Too Much (Machine): Sewing back and forth many times creates a very thick, messy area of stitches. This can look bad and might even weaken the fabric over time by poking too many holes. 3-5 stitches forward and back is plenty.
• Knots Too Far From Fabric (Hand): If your finishing knot is not pulled tight against the fabric surface (or hidden just below it), it can snag and come undone. Pull the knot snug.
• Not Repeating Hand Knots: A single knot, especially with thinner thread, isn’t always enough to tie off sewing thread securely. Repeating the knot 2-3 times in the same spot makes it much stronger.
• Cutting Threads Too Short: If you cut the thread right against the knot, the end can sometimes slip through the knot, causing it to unravel. Leave a tiny tail (about 1/8 inch or 2-3 mm) or, better yet, hide the thread end by running it into the fabric or seam allowance.
• Ignoring Stress Points: Areas like corners, waistbands, or where handles attach need extra secure sewing stitches. Always reinforce these spots with good backstitching or extra hand knots/stitches.

Preventing sewing seam unraveling starts with careful finishing stitches. Taking the time to do it right saves you trouble later.

Tools That Help

Certain tools can make securing your thread ends easier and more effective.

• Good Quality Thread: Strong, smooth thread is less likely to break and knots better.
• Sharp Scissors/Snips: Cutting thread cleanly close to the fabric or knot requires sharp tools. Embroidery snips are great for this.
• Hand Sewing Needles: Choose a needle size appropriate for your thread. A needle with an eye large enough for your thread is essential for making hand sewing knots and burying thread tails.
• Needle Grabber/Puller: If you’re working with thick fabric or buried threads, a small rubber gripper can help pull the needle through.
• Loop Turner (for burying tails in tubes): While not strictly for knots, a loop turner can help pull thread tails inside fabric tubes (like straps) to hide and secure them.
• Fray Check (liquid seam sealant): A tiny drop on a knot or backstitch can add extra security, especially on fabrics that fray easily. Use very sparingly as it can stiffen or discolor fabric.

Using the right tools makes implementing these sewing knot techniques simpler and more successful.

How Fabric Affects Finishing

The type of fabric you are sewing on can impact how you finish your seams.

• Heavy Fabrics (Denim, Canvas): Require strong locking stitches. Machine backstitching should be solid. Hand knots need to be firm and possibly repeated more times. Burying thread tails in the fabric is effective due to the thickness.
• Lightweight Fabrics (Silk, Rayon): Show knots and bulky backstitching easily. Prefer tiny backstitches or the machine lock stitch. Hand sewing hidden knots or careful reinforcing stitches are best. Avoid thick knots that pull or pucker the delicate fabric.
• Fray-Prone Fabrics (Linen, some Cottons): Need extra security. Backstitching or reinforced hand stitches are crucial. Consider using fray check on knots or ends within the seam allowance (not on visible areas). Burying thread tails is highly recommended.
• Stretchy Fabrics (Knits): Machine stitches often need to be done with a stretch stitch or serger. Finishing requires these stitches to be secured, often by sewing over the tail threads with a few extra stitches within the seam allowance or using a stretch-safe hand knot like a surgeons knot variation (though simpler methods usually suffice for securing ends). Standard backstitching on a regular machine can break knit threads, so use a stretch stitch for backstitching or a dedicated lock stitch.

Always test your finishing stitch method on a scrap of your fabric before applying it to your project.

The Importance of Practice

Mastering how to finish a sewing knot and secure thread end comes with practice. Try different sewing knot techniques on scrap fabric. See how your machine’s backstitch looks. Practice making hand knots – both visible and hidden. The more you practice, the easier and neater your finishing stitches will become. Strong finishes are a hallmark of a well-made garment or project. They show attention to detail and ensure your hard work lasts. Learning to tie off sewing thread effectively is a fundamental skill that elevates your sewing from good to great. These secure sewing stitches are the quiet heroes of durable seams, preventing sewing seam unraveling stitch by stitch.

Deciphering Sewing Pattern Instructions

Sewing patterns often have instructions on how to finish seams, but they might use different terms. “Secure stitching,” “reinforce,” “backtack,” or “lock stitch” usually mean you need to tie off sewing thread or add locking stitches at the start and end. If a pattern just says “sew seam,” it’s implied you need to secure the ends unless it’s a temporary seam or one that will be crossed by another seam later. When in doubt, using one of the secure sewing stitches methods described here is always a good idea to prevent sewing seam unraveling.

Comparing Machine vs. Hand Finishing

Both machine and hand sewing require you to secure thread ends, but the methods differ.

• Machine Finishing: Relies mainly on backstitching or machine-made locking stitches. It’s fast and provides a strong bar of stitches. Best for long seams, speed, and general construction.
• Hand Finishing: Relies on making physical knots or small, repeated stitches. It allows for more precision, is less bulky in delicate areas, and is essential for areas you can’t reach with a machine or for visible details. Best for repairs, detailing, delicate fabrics, and areas requiring a hidden finish.

Both sets of sewing knot techniques are valuable. A skilled sewer knows when to use which, or even combine them (e.g., machine sew a seam, then hand-sew the thread tails for extra neatness).

A Look at Knot Security

Let’s look briefly at why certain knots or stitch patterns are secure.

• Knots: A knot works by using friction. When pulled, the loops of thread tighten against each other and the fabric, creating resistance that stops the thread from moving. Repeating the knot or adding more loops increases this friction and security.
• Backstitching/Reinforcing Stitches: These create a block of thread by sewing over the same point multiple times. This makes it hard for the thread to pull through the fabric’s weave. It’s like building a small, dense barrier of thread. These act as locking stitches, trapping the end.
• Burying Thread Tails: By running the thread tail through existing stitches or within the fabric layers, you use the fabric itself and the surrounding threads to hold the end in place through friction.

Each of these methods works to secure the thread end and prevent sewing seam unraveling using different principles of tension and friction.

Final Thoughts on Stitch Security

The secret to strong finishing stitches is simply taking the time to do them properly. Whether it’s a quick backstitch on a machine or a careful hand sewing knot, securing your thread is a small step that makes a big difference in the lifespan of your project. Don’t skip this step! Practice your sewing knot techniques, choose the right method for your fabric and project, and enjoy sewing things that truly last. Knowing how to tie off thread effectively means your secure sewing stitches will stand up to wear and tear, preventing sewing seam unraveling and keeping your creations intact.

Frequently Asked Questions About Finishing Stitches

Here are answers to some common questions about how to secure thread ends.

H5 What is the best way to tie off sewing thread?
The best way depends on if you are hand sewing or machine sewing, and the fabric. For machine sewing, backstitching at the start and end is standard. For hand sewing, a secure knot pulled tight against the fabric (or hidden) or reinforcing stitches are best. The goal is always to create secure sewing stitches.

H5 How short can I cut my thread tails after knotting?
Do not cut them right against the knot. Leave a small tail of about 1/8 inch (2-3 mm). For extra security, bury the thread tail within the fabric layers or seam allowance instead of just cutting it.

H5 Can I use fabric glue instead of a knot?
A tiny dot of fabric glue can secure thread ends, especially on fraying fabrics or in places where a knot is not suitable. However, it should be used sparingly, on the back of the fabric, and is not a substitute for proper knotting or backstitching in high-stress areas. It can make the fabric stiff or discolor it.

H5 My machine’s backstitch is messy. What can I do?
Try reducing the stitch length for your backstitch. A shorter stitch makes a denser, neater reinforcement. Also, make sure you are only backstitching 3-5 stitches, not more. Some machines just do a cleaner backstitch than others. Consider using the machine’s lock stitch function if it has one.

H5 Should I knot the thread when starting hand sewing?
Yes, usually. An ‘Away Knot’ or similar hand sewing knot at the very end of your thread is essential to anchor your first stitch. You can also start with a few tiny backstitches to anchor the thread without a visible knot on the right side.

H5 What are locking stitches?
Locking stitches are stitches that are secured in place to prevent unraveling. This can be achieved through machine backstitching, a dedicated machine ‘lock stitch’ function (which sews tiny stitches on top of each other), or by hand sewing knot techniques like repeated knots or reinforcing stitches. The purpose is to secure the thread end.

H5 How do I prevent sewing seam unraveling effectively?
The primary way is to use strong finishing stitches at the start and end of every seam. This means proper backstitching (machine) or secure hand sewing knots and reinforcing stitches (hand sewing). Also, finishing the raw edges of your fabric (like with a serger, zigzag stitch, or pinking shears) helps prevent the fabric itself from fraying and pulling the stitches loose.

H5 Is there a trick for making small hand sewing knots?
Practice helps! When making the knot, pull the thread slowly and guide the knot down to the fabric surface with your fingertip or a pin tip. Don’t yank it fast. Repeating the knot in the same spot helps build security without making a huge, bulky knot. The hidden knot method is also great for making the finish less noticeable.
