What is a Blind Hem?
A blind hem is a sewing stitch that appears almost invisible on the right side of the fabric. It’s achieved by catching only a few threads of the main fabric as the needle goes through the folded hem. This differs from a standard hem where stitches are clearly visible on the right side. It’s a staple for creating polished finishes on trousers, skirts, dresses, and even home decor items like curtains.
Why Use a Blind Hem?
The primary reason to use a blind hem is for its aesthetic appeal. It provides a clean, unmarred finish on the right side of the fabric, making your handmade items look store-bought. Beyond aesthetics, a blind hem is also quite durable and can prevent fraying effectively. It’s particularly useful for delicate fabrics where visible stitches might detract from the material’s beauty or even cause damage.
Gathering Your Supplies
Before you start, make sure you have the right tools. Having everything ready will make the process much smoother.
Essential Sewing Tools
- Sewing Machine: Any standard sewing machine can do a blind hem, but some have built-in blind hem stitches.
- Blind Hem Stitch Settings: You’ll need to know how to set your machine to the correct stitch.
- Blind Hemming Foot (Optional but Recommended): This special presser foot is designed to guide the fabric for blind hemming and makes the process significantly easier and more accurate.
- Thread: Choose thread that matches your fabric.
- Fabric: Your project fabric.
- Iron and Ironing Board: Crucial for pressing the hem.
- Measuring Tape or Ruler: For accurate hem folding.
- Fabric Scissors: For trimming.
- Pins: To hold the hem in place.
- Seam Ripper (Just in case!): Always good to have on hand.
Setting Up Your Sewing Machine for Blind Hemming
The key to a successful blind hem is correctly setting up your sewing machine. This involves selecting the right stitch and, if you have one, attaching the blind hemming foot.
Selecting the Right Blind Hem Stitch
Most modern sewing machines offer a specific blind hem stitch. This stitch is characterized by a straight stitch that periodically jumps over to catch a few threads of the main fabric before returning to the hem fold.
How to Identify the Blind Hem Stitch:
- Look for a stitch that resembles a lightning bolt or a zigzag that is very narrow and angled.
- Consult your sewing machine’s manual. It will clearly label the blind hem stitch and explain its function.
Blind Hem Stitch Settings:
The exact settings will vary depending on your machine, but here are general guidelines:
| Setting | Recommendation |
|---|---|
| Stitch Type | Blind Hem Stitch (often indicated by a symbol like a dashed zigzag or a lightning bolt) |
| Stitch Length | Medium (around 2-3 mm). Adjust based on fabric thickness. |
| Stitch Width | Narrow (usually around 0-1.5 mm). This is critical for catching only a few threads. |
| Tension | Usually, normal tension (around 4-5) works well. Test on a scrap first. |
Important Note: Always test your blind hem stitch settings on a scrap piece of your fabric before sewing your actual project. This allows you to fine-tune the width and length to ensure you’re catching just a few threads and the stitch is almost invisible from the right side.
Using the Blind Hemming Foot
A blind hemming foot, also known as a blind hem presser foot, is designed with a small metal guide. This guide helps keep the folded fabric edge consistently positioned under the needle, ensuring each stitch catches the correct amount of fabric.
Attaching the Blind Hemming Foot:
- Disengage the old foot: Lower the presser foot lever and remove the current presser foot according to your machine’s instructions.
- Position the new foot: Place the blind hemming foot onto the presser bar, ensuring the metal guide is positioned correctly.
- Secure the foot: Raise the presser foot lever and attach the blind hemming foot with the screw, as per your machine’s manual.
How to Use the Blind Hemming Foot:
- The folded edge of your fabric will rest against the metal guide on the foot.
- As you sew, the needle will swing. When it swings to the left, it will catch a few threads of the main fabric. When it swings to the right, it will go through the folded edge of the hem.
Preparing Your Fabric for Blind Hemming
Proper preparation is key to a neat blind hem. This involves measuring, folding, and pressing your hem correctly.
Measuring and Marking the Hemline
- Determine Hem Depth: Decide how deep you want your finished hem to be. This depends on the garment and fabric. A typical hem depth for skirts and dresses might be 1-2 inches.
- Measure and Mark:
- With the wrong side of the fabric facing you, measure down from the raw edge the desired finished hem depth PLUS the amount you want to fold for the initial turn. For example, if you want a 1.5-inch finished hem and will fold up 0.5 inches initially, you’ll mark 2 inches from the raw edge.
- Use a measuring tape or ruler and a fabric marker or chalk to mark a straight line all the way around your project. Ensure the line is parallel to the bottom edge.
Folding and Pressing the Hem
This is a critical step for a professional finish.
- First Fold: Fold the raw edge of the fabric up to meet your marked hemline. Press this fold firmly. This encloses the raw edge.
- Second Fold: Now, fold the fabric again, this time so the folded edge (which was the raw edge) meets the original raw edge of the fabric. Essentially, you are folding the fabric onto itself, creating a double-fold hem. The depth of this second fold will be your desired finished hem depth.
- Using the Blind Hemming Foot Guide: If using a blind hemming foot, you’ll want the folded edge to be positioned against the metal guide. The width of this fold should be consistent. You might need to adjust your initial folds to accommodate the foot’s guide. A common method is to fold up the raw edge about 1/4 to 1/2 inch, press, then fold up again so the raw edge is encased within the fold, and the folded edge meets the raw edge of the garment body. The width of this final fold will then dictate how much fabric the blind stitch catches.
- Press Again: Press this second fold very firmly. A well-pressed hem is essential for guiding the fabric correctly under the blind hemming foot and ensuring a flat, smooth finish.
Pinning the Hem
Once pressed, carefully pin the hem in place.
- Pin Placement: Pin along the folded edge of the hem, through all layers. The pins should be perpendicular to the folded edge.
- Pin Tip: Try to catch the fabric just above the fold, ensuring the pins don’t interfere with the blind hemming foot’s guide.
Sewing the Blind Hem: Step-by-Step
Now you’re ready to sew! This is where the magic happens.
Step 1: Position the Fabric Under the Foot
- Lower the Presser Foot: Place the fabric under the blind hemming foot with the folded edge of the hem aligned against the metal guide on the foot.
- Ensure Correct Orientation: The right side of your fabric should be facing upwards, and the folded edge of the hem should be resting against the guide. The needle should be positioned to the left of the guide.
Step 2: Sewing the Machine Blind Stitch
- Start Sewing: Begin sewing slowly, allowing the fabric to feed smoothly.
- Monitor the Needle: As you sew, watch the needle.
- When the needle swings to the left, it should catch just a few threads of the main fabric (the garment body).
- When the needle swings to the right, it should go directly through the folded edge of the hem.
- Guide the Fabric: Use your hands to gently guide the fabric, keeping the folded edge firmly against the metal guide of the blind hemming foot. Do NOT push or pull the fabric. Let the machine feed it.
- Continue to the End: Sew around the entire hem, maintaining consistent fabric feeding and edge alignment.
- Backstitch: When you reach the end, backstitch a few stitches to secure the end of the seam.
Step 3: Finishing the Blind Hem
- Remove Pins: Carefully remove all pins as you sew over them, or before you start if you prefer.
- Trim Threads: Trim any loose threads.
- Inspect: Turn the fabric to the right side. You should see a very fine, almost invisible stitch line where the needle caught the fabric. The folded hem edge should be securely attached without any obvious stitches showing.
- Final Press: Turn the fabric back to the wrong side and press the hem firmly. You can press from the right side as well, being careful not to flatten the stitches too much.
Troubleshooting Common Blind Hemming Issues
Even with the best preparation, you might encounter a few common problems. Here’s how to fix them:
Issue: Stitches are too visible on the right side.
- Cause: The needle is catching too much fabric.
- Solution:
- Adjust Stitch Width: Decrease the stitch width on your sewing machine. Aim for the narrowest setting that still allows the needle to swing.
- Adjust Fabric Fold: Ensure you are only catching 1-3 threads of the main fabric. You might need to refold and press your hem slightly differently, ensuring the folded edge is narrower or positioned more precisely against the foot’s guide.
- Check Blind Hemming Foot: Make sure the foot is correctly attached and the fabric is against the guide.
Issue: Stitches are breaking or skipping.
- Cause: Thread tension is too tight, needle is dull, or fabric is too thick for the setting.
- Solution:
- Check Thread Tension: Slightly decrease the upper thread tension.
- Change Needle: Ensure you are using a sharp, appropriate needle for your fabric type (e.g., universal, ballpoint, or microtex).
- Adjust Stitch Length: Slightly increase the stitch length if the fabric is bulky.
Issue: Hem is wavy or puckered.
- Cause: Fabric was stretched while sewing, or the hem wasn’t pressed well.
- Solution:
- Don’t Stretch Fabric: Gently guide the fabric but avoid stretching or pulling it as you sew.
- Press Meticulously: Ensure all folds are pressed crisply and accurately before sewing.
- Test Feed: If your machine has adjustable feed dogs, slightly lowering them might help prevent stretching on delicate fabrics.
Issue: Needle hits the blind hemming foot’s guide.
- Cause: Incorrect needle or stitch selection, or the foot is not aligned properly.
- Solution:
- Verify Stitch: Double-check that you are using the correct blind hem stitch.
- Check Needle: Ensure the needle is centered and correctly installed. Some machines might require a specific needle plate or needle for certain blind hem stitches. Consult your manual.
- Foot Alignment: Re-attach the blind hemming foot, making sure it’s properly seated.
Alternatives to the Blind Hemming Foot
While the blind hemming foot is highly recommended, you can achieve a blind hem without it, though it requires more practice and precision. This is sometimes referred to as sewing a machine blind stitch without the specialized foot.
Sewing Blind Hem Without a Blind Hemming Foot
- Prepare your hem: Fold and press your hem as usual (first fold, then second fold to encase the raw edge). Pin securely.
- Set up your machine: Select the blind hem stitch on your sewing machine. Set the stitch length to medium and the stitch width to very narrow.
- Position the fabric: Place the fabric under your regular presser foot. Position the folded edge of the hem so it’s about 1-2 mm away from the center needle position.
- Sew carefully: As you sew, you will need to manually guide the fabric.
- The needle will swing left and right.
- When the needle swings to the left, you want it to catch just a few threads of the main fabric.
- When the needle swings to the right, it should stitch directly into the folded edge of the hem.
- You will need to slightly pivot or move the fabric with your hands as you sew to ensure the right swing catches the fabric and the left swing stitches the fold.
- Practice is Key: This method requires significant practice to get consistent results. Aim to catch a few threads on the left swing and stitch the fold on the right swing.
Specific Fabric Considerations for Blind Hemming
Different fabrics require slightly different approaches to achieve the best blind hem.
Delicate Fabrics (Silk, Chiffon, Voile)
- Preparation: Press seams gently with a pressing cloth to avoid scorching.
- Stitch Settings: Use a finer needle (size 60/8 or 70/10). Slightly increase stitch length if needed to prevent tearing. Use a lower presser foot pressure if your machine allows.
- Blind Hemming: Be extra careful to catch only the barest minimum of threads on the right side. The blind hemming foot is particularly useful here.
Heavier Fabrics (Denim, Wool, Twill)
- Preparation: You might need to trim down the bulk of the folded hem edge before sewing, especially if it’s a double-fold hem.
- Stitch Settings: Use a medium to heavy-duty needle (size 80/12 or 90/14). Ensure your machine has enough power to handle the layers. You might need a slightly longer stitch length.
- Blind Hemming: Ensure the needle is strong enough to penetrate the fabric layers without breaking.
Knits
- Preparation: Knits can stretch out of shape. Ensure you press the folds firmly and don’t pull the fabric as you sew. A knit fabric might require a different type of hem, like a double needle hem or a serged hem. However, a blind hem can be done if care is taken.
- Stitch Settings: Use a ballpoint or stretch needle. A very narrow zigzag stitch or a stretch blind hem stitch (if available) might be more suitable than a traditional blind hem stitch, as it allows for some stretch.
- Blind Hemming: Gently guide the fabric. Avoid stretching. The blind hemming foot can help keep the fabric stable.
