Hemming knit fabric can be a challenging task, as this type of fabric is known for its stretchiness. However, with the right techniques and a little patience, you can achieve perfect results and create beautifully finished garments. In this article, we will explore some tips and techniques that will help you hem knit fabric like a pro.
One important tip to keep in mind when hemming knit fabric is to use a stretch needle. These needles have a rounded point which helps prevent skipped stitches and fabric damage. By using a stretch needle, you can ensure that your hem will be secure and durable.
Another technique that can be useful when hemming knit fabric is using a twin needle. A twin needle creates two parallel lines of stitching, mimicking the look of a coverstitch. This not only adds a professional touch to your hem but also helps the fabric maintain its stretch. When using a twin needle, make sure to select the appropriate stitch on your sewing machine and adjust the tension accordingly.
Lastly, it’s important to choose the right hemming method for your knit fabric. While a traditional turned hem may work for some fabrics, others may require a more stretchy hem. One technique to consider is using a narrow zigzag stitch or a stretch stitch. These stitches allow the fabric to stretch while providing a secure finish. Experiment with different hemming methods to find the one that works best for your specific fabric.
Selecting the Right Stitch
When hemming knit fabric, it’s important to choose the right stitch to ensure a secure finish that won’t stretch or pucker. Here are some popular stitch options for hemming knit fabric:
- Straight Stitch: The straight stitch is a basic stitch commonly used for hemming woven fabrics. However, it is not recommended for knit fabric as the lack of stretch in the stitch can cause the hem to break when the fabric stretches.
- Zigzag Stitch: The zigzag stitch is a versatile option for hemming knit fabric. It has some stretch, allowing the hem to move with the fabric without breaking. Set your sewing machine to a zigzag stitch with a medium width and length to achieve a secure hem.
- Twin Needle Stitch: The twin needle stitch creates parallel rows of straight stitches on the right side of the fabric and a zigzag stitch on the wrong side. This stitch adds a decorative touch to the hem while providing stretch and preventing puckering. Be sure to use a ballpoint twin needle specifically designed for knit fabric.
When selecting the right stitch, it’s also important to consider the weight and stretchiness of your knit fabric. Test different stitches on scrap fabric to determine which stitch works best for your specific project.
| Stitch Type | Stretch | Strength | Appearance |
|---|---|---|---|
| Straight Stitch | Little to no stretch | Weaker, prone to breaking | Simple and minimal |
| Zigzag Stitch | Moderate stretch | Strong and secure | Visible zigzag pattern |
| Twin Needle Stitch | Good stretch | Strong and secure | Parallel rows with zigzag on the back |
By selecting the right stitch for hemming knit fabric, you can achieve a professional-looking finish that is both durable and flexible.
Preparing the Fabric
Before you begin hemming your knit fabric, it’s important to properly prepare the fabric to ensure the best results. Follow these steps to get your fabric ready:
- Wash and dry the fabric: Start by washing your knit fabric according to the care instructions on the label. This will remove any dirt, oils, or chemicals that may be present on the fabric. After washing, tumble dry the fabric on a gentle or low heat setting or air dry it.
- Press the fabric: Once the fabric is dry, press it with an iron to remove any wrinkles. Set the iron to the appropriate heat setting for your fabric, taking care not to use too high of a heat as this can damage or stretch the knit fabric. Use a pressing cloth or press the fabric from the wrong side to avoid leaving shiny marks or imprints.
- Trim the edges: After pressing, trim any uneven or frayed edges of the fabric. This will help ensure that your hemline is even and neat.
- Mark the hemline: Use a fabric marker or tailor’s chalk to mark the desired hemline on your fabric. You can either measure and mark a specific length from the edge of the fabric or use a ruler or measuring tape to ensure an even hemline.
- Secure the fabric: To prevent the knit fabric from stretching out while hemming, you can secure the edges by using small clips, pins, or basting stitches. This will help keep the fabric in place and maintain the desired shape during the hemming process.
Measuring and Marking
Measuring accurately is crucial when hemming knit fabric to achieve a professional and polished result. Here are some tips for measuring and marking your fabric:
- Use a tape measure: Start by measuring the desired length of your garment. Use a flexible tape measure to get an accurate measurement. It is important to measure from the bottom edge of the fabric to ensure an even hem.
- Consider the stretch: Keep in mind that knit fabric has stretch, so your garment might appear longer or shorter when worn. Take into account how the fabric will stretch when measuring the length.
- Pin and try on: Pin the fabric at the desired length and try on the garment to ensure it falls at the right spot. Adjust the pinning if necessary before marking the fabric.
- Use fabric markers: Once you have determined the correct length, use fabric markers to mark the hemline. Make sure to use a marker that is suitable for your fabric and will wash out easily.
- Parallel lines: If you prefer a folded hem, mark parallel lines around the fabric at the desired length. These lines will serve as a guideline when folding the fabric.
- Be consistent: Take your time to measure and mark each section of the fabric accurately. Consistency is key to achieving an even and professional-looking hem.
By following these measuring and marking techniques, you will ensure that your knit fabric hem is neat and precise, adding value and style to your handmade garments.
Using a Double Needle
A double needle is a useful tool for hemming knit fabric because it allows you to create a professional-looking finish with two rows of parallel stitches. Here are the steps to use a double needle for hemming:
- Choose the right double needle: Double needles come in different widths, so select one that matches the width you want for your hem. For a narrower hem, use a narrow double needle, and for a wider hem, use a wider double needle.
- Prepare your fabric: Fold up the raw edge of your knit fabric to the desired hem width, and press it with an iron. Then, pin the folded edge in place to keep it secure.
- Set up your sewing machine: Insert the double needle into your sewing machine, making sure it is securely in place. Thread each needle using a separate spool of thread and pass them through the corresponding needle guides.
- Adjust the tension: Check the tension setting on your sewing machine and adjust it if necessary. It’s important to have balanced tension to ensure even stitches on both sides.
- Test on scrap fabric: Before hemming your actual garment, test the double needle on a scrap piece of fabric to ensure it is creating the desired stitch and tension.
- Sew the hem: Align the folded edge of your fabric under the sewing machine presser foot, positioning it so that the twin needles will stitch along the folded edge. Begin sewing, using a steady and even pace to create two rows of parallel stitches.
- Finish the ends: When you reach the end of your hem, continue sewing past the edge of the fabric. This will help secure the stitches and prevent unraveling. Trim any excess thread.
- Press the hem: After hemming, press the hem with an iron to help it lay flat and give it a professional finish.
Using a double needle can take your knit fabric hemming to the next level. The twin rows of stitches create a polished look and add extra security to the hem. Practice on scrap fabric before attempting it on your garment to master the technique.
Using a Walking Foot
When it comes to hemming knit fabric, using a walking foot can make a huge difference in achieving perfect results. A walking foot is a sewing machine foot that has built-in feed dogs to help evenly feed the fabric through the machine.
Here are some tips and techniques for using a walking foot when hemming knit fabric:
- Attach the walking foot to your sewing machine: Start by removing the standard presser foot from your sewing machine and attaching the walking foot. Consult your sewing machine’s manual for specific instructions on how to attach the walking foot.
- Select the appropriate stitch: Knit fabric requires a stretch stitch or a zigzag stitch to allow the fabric to stretch without breaking the stitches. Choose a stitch that is suitable for stretch fabrics and set the stitch length and width according to your fabric and desired hem width.
- Prepare the fabric: Before hemming, it is important to prepare the fabric properly. Make sure the fabric is clean and pressed, and mark the hemline using tailor’s chalk or fabric marker if necessary.
- Start sewing from a side seam: It is best to start sewing the hem from a side seam rather than the front or back of the garment. This will help hide any unevenness or inconsistencies in the hem.
- Slow and steady: When sewing with a walking foot, it is important to take your time and sew slowly. This will ensure that the fabric is fed evenly through the machine and prevent any stretching or distortion.
- Use a gentle touch: While sewing, make sure to guide the fabric gently but firmly. Avoid pulling or tugging on the fabric, as this can lead to stretching or distortion. Let the walking foot do the work of moving the fabric through the machine.
- Finish the hem: Once you have sewn the hem, press it gently to set the stitches. You can also trim any excess fabric if necessary. If desired, you can also finish the raw edge of the hem with a serger or a zigzag stitch to prevent fraying.
Using a walking foot can help you achieve professional-looking hems on knit fabric. Follow these tips and techniques for best results and enjoy sewing with knit fabrics!
Sewing the Hem
Once you have measured and marked your hem, it’s time to sew it in place. Follow these steps for a perfect hem on your knit fabric:
- Gather your supplies: You will need a sewing machine, matching thread, pins, and a ballpoint or stretch needle.
- Prepare your sewing machine: Set your sewing machine to a straight stitch and adjust the stitch length to a medium length. Insert a ballpoint or stretch needle, as these are designed for sewing on knit fabrics.
- Pinning: Start by folding the raw edge of your hem up to the marked line and pinning it in place. Use as many pins as necessary to secure the fabric and prevent shifting while sewing.
- Sewing the hem: Begin sewing along the folded edge of the hem, removing the pins as you go. Be sure to backstitch at the beginning and end of your stitching to secure the thread. Keep a steady pace and guide the fabric with your hands to ensure an even and straight stitch.
- Finishing: Once you have sewn all the way around the hem, backstitch again to secure the thread. Trim any excess thread and gently press the hem with an iron to give it a professional finish.
Remember to always test your stitch on a scrap piece of fabric before sewing your hem, as knit fabrics can behave differently than woven fabrics. With the right techniques and a bit of practice, you’ll be hemming knit fabric like a pro in no time!
