What is a Blind Hem?
A blind hem is a type of hem where the stitches are almost invisible on the right side of the fabric. This is achieved by catching only a few threads of the main fabric with each stitch. It’s perfect for lightweight to medium-weight fabrics and is commonly used on trousers, skirts, dresses, and curtains. The goal of a blind hem is to provide a secure hem without the bulk or visible stitching that can detract from the garment’s appearance.
Why Choose a Blind Hem?
The allure of the blind hem lies in its subtlety. Unlike a double-folded hem with visible topstitching, the blind hem offers a clean, unmarred finish.
- Aesthetic Appeal: The primary reason to choose a blind hem is its clean and professional look. It doesn’t distract from the fabric or the design of the garment.
- Fabric Versatility: It works well on a wide range of fabrics, from delicate silks to sturdier cottons, as long as the fabric isn’t too thick or bulky.
- Durability: When sewn correctly, a blind hem is surprisingly durable, holding the hem securely in place without unraveling.
- Time-Saving: While it might seem intricate, learning to sew a blind hem on a sewing machine can actually save you time compared to hand-sewing an invisible hem, especially for longer seams.
Essential Tools for Sewing a Blind Hem
Before you start sewing, gather these crucial items. Having everything ready will make the process much smoother.
- Sewing Machine: Any standard sewing machine can sew a blind hem.
- Blind Hem Foot (or Zigzag Foot): This is the most important accessory. A blind hem foot is specially designed to guide the fabric and help you catch just a few threads. If your machine didn’t come with one, they are widely available and relatively inexpensive. Sometimes, a standard zigzag foot can be used, but the results may not be as clean.
- Fabric Shears or Rotary Cutter and Mat: For precise fabric cutting.
- Iron and Ironing Board: Essential for pressing seams and hems.
- Measuring Tape or Ruler: For accurate measurements.
- Fabric Marker or Chalk: To mark your hemline.
- Straight Pins: For securing the fabric.
- Thread: Choose a thread that matches your fabric. For an extra invisible hem, you can use monofilament (nylon) thread on the bobbin or even in the needle for very fine fabrics, though this requires careful tension adjustment.
- Seam Ripper: For any inevitable mistakes.
Preparing Your Fabric for a Blind Hem
Proper preparation is key to achieving a beautiful blind hem. Don’t skip these steps!
1. Wash and Dry Your Fabric
Always pre-wash and dry your fabric according to its care instructions. This prevents shrinkage after you’ve sewn the garment or item.
2. Press Your Fabric
A well-pressed fabric makes it easier to cut and sew accurately. Iron out any wrinkles.
3. Determine Hem Depth and Mark
Decide how deep you want your hem to be. Consider the garment’s style and the fabric’s weight.
* Measure: Measure from the finished hem edge upwards to create your hem allowance.
* Mark: Use a fabric marker or chalk to draw a clear line on the wrong side of the fabric. This line is where you will fold your hem.
4. Cut Excess Fabric (If Necessary)
If your hem allowance is excessively wide, you might want to trim it to a more manageable width after marking. For a standard blind hem, an allowance of 1 to 2 inches is usually sufficient.
5. Fold and Press the Hem
This is a crucial step for creating a neat blind hem.
- First Fold: On the wrong side of the fabric, fold the raw edge up to meet your marked hemline. Press this fold firmly.
- Second Fold: Now, fold the fabric again, so the raw edge is enclosed. The amount you fold here determines how far the fabric edge will be from the folded edge of the hem. This fold should be made so that when you place the fabric under the blind hem foot, the needle will catch just a few threads of the main fabric outside of this folded edge.
- Tip: For a truly invisible hem, the folded edge should be about 1/8 to 1/4 inch away from the edge of the fold you just pressed. The blind hem foot’s guide will help you maintain this consistent distance.
- Press Again: Press this second fold very crisply.
6. Pin the Hem in Place
Carefully pin the folded hem to the main body of the garment or fabric. The pins should go through the folded hem and just into the main fabric, keeping the folded edge as flat as possible.
Setting Up Your Sewing Machine for the Blind Stitch
Now it’s time to get your sewing machine ready.
1. Attach the Blind Hem Foot
Replace your regular presser foot with the blind hem foot. This foot has a small metal or plastic guide in the center. This guide is what will help you catch the fabric threads.
2. Select the Blind Hem Stitch
Most sewing machines have a specific “blind stitch” or “blind hem stitch.” Consult your machine’s manual to locate it. This stitch typically looks like a zigzag stitch that is very narrow on one side and wider on the other.
- Blind Stitch Settings:
- Stitch Width: You’ll usually set the stitch width to a medium to wide setting (e.g., 3-5). This wider part of the stitch will catch the main fabric.
- Stitch Length: A stitch length of 2-3 mm is a good starting point. You want the stitches to be close enough together to be secure but not so close that they create bulk.
- Needle Position: Some machines allow you to adjust the needle position. You might need to experiment to find the sweet spot where the wider part of the stitch lands on the main fabric.
3. Thread Your Machine
Use a good quality thread that matches your fabric. Ensure your machine is threaded correctly, and the tension is balanced.
Sewing the Blind Hem: Step-by-Step
With your machine set up and fabric prepared, you’re ready to sew.
Step 1: Position the Fabric
- Turn the fabric so the wrong side is facing you.
- Place the folded hem under the blind hem foot. The folded edge of the hem should be resting against the center guide of the blind hem foot.
- The main fabric (the part that will be caught by the stitch) should be to the left of the guide. The folded edge of the hem itself should be to the right of the guide.
Step 2: Adjust the Guide
- This is the most critical part of how to blind hem. The guide on the foot should be positioned so that when the needle swings to the left (the wider part of the stitch), it catches only a few threads of the main fabric – the fabric that is not folded.
- When the needle swings to the right (the narrower part of the stitch), it should stitch directly into the folded edge of the hem.
- Test: Before sewing on your actual project, always test the stitch on a scrap piece of the same fabric. Adjust the stitch width and needle position until you achieve the desired result. The stitch should look like a small bar tack on the folded edge and a tiny straight stitch on the main fabric.
Step 3: Begin Sewing
- Lower the presser foot.
- Start sewing slowly. Guide the fabric gently, keeping the folded edge snug against the blind hem foot’s guide.
- The machine will automatically create the blind stitch: a few straight stitches into the fold, then a wider zigzag that catches a few threads of the main fabric, and then back to the fold.
Step 4: Continue Along the Hem
- Sew continuously around the entire hem.
- Pivot at Corners: If you encounter a corner, sew up to the corner, leave the needle down in the fabric, lift the presser foot, pivot the fabric, lower the presser foot, and continue sewing.
Step 5: Finish Sewing
- When you reach the beginning of the hem, backstitch a few stitches to secure the seam.
- Lift the presser foot, pull the fabric out, and snip the threads.
Finishing Touches for Your Blind Hem
You’re almost there! These final steps will perfect your invisible hem.
1. Remove Pins
Carefully remove all the pins you used to hold the hem in place.
2. Turn and Press
- Turn the fabric right side out.
- Gently push the hem away from the main fabric.
- Press the hem flat. You’ll see that the stitches are hardly visible on the right side. The press should be firm, ensuring the hem lies smoothly.
3. Inspect Your Work
Look at the right side of the fabric. You should see only occasional tiny stitches, if any. The hem should lie flat and smooth.
Common Issues and Troubleshooting
Even with the best intentions, you might encounter a few hiccups. Here’s how to fix them.
Issue: Visible Stitches on the Right Side
- Cause: The zigzag stitch is catching too much of the main fabric, or the guide isn’t positioned correctly.
- Solution:
- Adjust the blind hem foot’s position to catch fewer threads.
- Try a narrower stitch width.
- Ensure you are only catching 1-2 threads of the main fabric with the wider part of the stitch.
- Check your fabric fold – if it’s too wide, it might make it harder for the stitch to stay hidden.
Issue: Hem is Puckering or Straining
- Cause: Tension is too high, or the stitch is too tight.
- Solution:
- Lower the upper thread tension slightly.
- Increase the stitch length slightly.
- Ensure you are not pulling or stretching the fabric as you sew.
Issue: Stitches are Falling Off the Fabric Edge
- Cause: The folded edge is not held securely against the guide, or the needle position is off.
- Solution:
- Ensure the folded edge of the hem is consistently pressed and held firmly against the guide of the blind hem foot.
- Adjust the needle position to be closer to the folded edge.
- Try a narrower stitch width.
Issue: Machine is Skipped Stitches
- Cause: Dull needle, incorrect needle type, or incorrect tension.
- Solution:
- Use a new, sharp needle appropriate for your fabric type (e.g., a universal needle for most fabrics, a ballpoint needle for knits, a sharp needle for silks).
- Check your bobbin winding and thread path.
- Adjust thread tension.
Variations and Tips for Different Fabrics
The blind hem is versatile, but certain fabrics require specific considerations.
Lightweight Fabrics (Silk, Chiffon, Voile)
- Challenge: These fabrics are slippery and can fray easily.
- Tips:
- Use a finer needle (size 70/10 or 65/9).
- Consider using a walking foot or rolling hem if the fabric is very sheer and the blind hem is too difficult.
- A test on a small scrap is essential.
- For extra precision, you can use a very fine monofilament thread in the bobbin.
Medium-Weight Fabrics (Cotton, Linen, Polyester Blends)
- Challenge: Generally easier to work with.
- Tips:
- A standard universal needle is usually fine.
- A good press is crucial to keep the folds crisp.
- The blind hem foot works very well on these fabrics.
Knit Fabrics
- Challenge: Knits are stretchy, and a standard blind stitch can break or distort the fabric.
- Tips:
- Use a ballpoint or stretch needle.
- Use a stretch blind hem stitch if your machine has one. If not, a regular blind stitch with a slightly longer stitch length and wider zigzag may work.
- Be careful not to stretch the fabric as you sew. You might need to use a stabilizer or a special stitch like a twin needle for a more elastic finish. For very stretchy knits, a serger’s rolled hem is often preferred.
Thick or Bulky Fabrics (Wool, Denim)
- Challenge: It can be difficult for the needle to penetrate, and the blind hem foot’s guide might not work effectively.
- Tips:
- A blind hem might not be the best choice for very thick fabrics. A simple double-folded hem with topstitching or a turned-up hem might be more practical and neater.
- If you must use a blind hem, consider trimming the seam allowance of the hem to reduce bulk.
- Use a heavier-duty needle.
- The folded edge might need to be pressed very flat, and you might need to use a hump jumper or a seam guide to get the foot over the thick fold.
Advanced Techniques and Considerations
Once you’ve mastered the basics of sewing a blind hem, you might want to explore more advanced aspects.
Using Monofilament Thread
Monofilament (nylon) thread is clear and almost invisible. It can be used on the bobbin or in the needle for an even more discreet blind stitch.
- When to Use: Best for lightweight and medium-weight fabrics where you want the absolute most invisible finish.
- Considerations:
- It can be slippery and prone to tangling if the tension isn’t right.
- It’s not as strong as regular polyester thread.
- Test tension carefully on a scrap. Use a slightly higher tension for the bobbin if using it on the bobbin.
Using a Twin Needle
For knit fabrics or for a decorative effect on wovens, a twin needle can create a beautiful, raised stitch that resembles a hand-stitched blind hem.
- How it Works: A twin needle has two needles attached to one shank. It stitches two parallel rows of straight stitches on top and a zigzag stitch underneath to connect them, creating a neat finish.
- Setup: You’ll need to set up your machine with two spools of thread. The zigzag stitch setting is crucial for the twin needle to work correctly. You may need to adjust tension settings.
- Blind Hemming with a Twin Needle: This requires a special twin needle blind hem stitch setting on some machines, or you manually set a wide zigzag stitch with the twin needle. The process is similar to a regular blind hem, but the stitch appearance is different.
Other Invisible Hem Techniques
While the machine blind stitch is efficient, other methods achieve an invisible hem:
- Hand-Sewn Blind Hem: This is the traditional method and often considered the most invisible, but it’s much slower. It involves carefully catching threads with a needle and thread.
- Rolled Hem: Often done with a serger or a special foot on a sewing machine, this creates a very narrow, small hem that can also appear quite subtle.
FAQ: Frequently Asked Questions About Blind Hemming
Here are answers to some common questions about sewing a blind hem.
Q1: What is the best stitch for a blind hem?
A1: The best stitch for a blind hem is the specific “blind stitch” or “blind hem stitch” found on most sewing machines. This stitch is a modified zigzag that stitches straight into the folded hem and then swings out to catch a few threads of the main fabric.
Q2: Do I need a special foot to sew a blind hem?
A2: Yes, while you can attempt a blind hem with a standard zigzag foot, a blind hem foot (also known as a blind stitch foot) is highly recommended. It has a guide that helps you catch the fabric threads accurately, leading to a much cleaner and more invisible hem.
Q3: Can I sew a blind hem on any fabric?
A3: You can sew a blind hem on most lightweight to medium-weight woven fabrics. It works best on fabrics that hold a crease well. Very lightweight, slippery, or stretchy fabrics can be challenging, and thick or bulky fabrics may be too difficult for the stitch to remain truly invisible or for the machine to handle easily.
Q4: How do I make the blind hem invisible?
A4: To make the blind hem invisible, you need to ensure that the wider part of the blind stitch catches only a few threads of the main fabric, not the folded edge. The folded edge should be pressed neatly against the guide of the blind hem foot, and the needle should swing out just enough to grab those outer threads. Testing on a scrap piece of fabric is crucial for adjusting the stitch width and needle position.
Q5: My blind hem stitches are visible on the outside. What can I do?
A5: If your stitches are visible, it likely means the zigzag stitch is catching too much of the main fabric. Try adjusting the stitch width to be narrower or repositioning the blind hem foot’s guide so it catches fewer threads. Ensure your folded edge is pressed neatly against the guide.
Q6: What is the difference between a blind stitch and a zigzag stitch?
A6: A standard zigzag stitch creates two lines of stitches that form a zigzag pattern. The sewing machine blind stitch is a specialized stitch that primarily stitches straight into the fold of the hem and then makes a single swing out to catch a few threads of the garment’s main fabric. This intermittent swing is what makes it nearly invisible from the outside. The blind stitch is designed for blind hemming, while a regular zigzag is for seams, decorative elements, or preventing fraying.
Q7: How do I sew an invisible hem by hand?
A7: Sewing an invisible hem by hand involves folding the hem allowance, pressing it, and then folding it again. You then use a very small stitch, catching just a thread or two of the main fabric with each stitch, and a slightly larger stitch into the folded hem edge. This requires patience and practice but can yield an exceptionally discreet finish. The machine blind stitch is the machine equivalent of this technique.
Conclusion
Mastering the machine blind hem is a valuable skill for any sewist. It elevates your finished projects by providing a clean, professional, and truly invisible hem. By following these steps, preparing your fabric carefully, and practicing with your sewing machine’s blind stitch and blind hem foot, you’ll be able to achieve beautiful results. Remember that practice makes perfect, so don’t be discouraged if your first attempt isn’t flawless. With a little patience and attention to detail, you’ll soon be sewing invisible hem finishes like a pro! Happy sewing!
