Sewing with stretchy fabric can be a daunting task, especially for beginners. One of the most critical factors in achieving a professional finish is using the right tension. In this article, we will delve into the world of stretchy fabrics, exploring the different types, their characteristics, and most importantly, the ideal tension settings for each.
Understanding Stretchy Fabric
Before we dive into the nitty-gritty of tension settings, it’s essential to understand the basics of stretchy fabric. Stretchy fabric, also known as knit fabric, is a type of fabric that has elasticity, allowing it to stretch and recover its shape. This property makes it ideal for garments that require a snug fit, such as activewear, swimwear, and hosiery.
Types of Stretchy Fabric
There are several types of stretchy fabric, each with its unique characteristics and requirements. Some of the most common types include:
- Jersey: A lightweight, single-knit fabric with a soft, smooth texture. Jersey is ideal for garments that require a comfortable fit, such as t-shirts and leggings.
- Interlock: A double-knit fabric with a thicker, more stable texture than jersey. Interlock is suitable for garments that require a bit more structure, such as sweatshirts and hoodies.
- Ribbing: A textured fabric with a ribbed pattern, often used for cuffs, waistbands, and neckbands. Ribbing is highly stretchy and provides a comfortable fit.
- Spandex: A synthetic fabric with high elasticity, often blended with other fibers to enhance stretch. Spandex is commonly used in activewear and swimwear.
Tension Settings for Stretchy Fabric
Now that we’ve explored the different types of stretchy fabric, let’s discuss the ideal tension settings for each. The tension setting on your sewing machine controls the amount of thread that is fed through the fabric, affecting the stitch length and density.
Tension Settings for Jersey Fabric
For jersey fabric, a lower tension setting is recommended. This allows for a smooth, even stitch that won’t pucker or distort the fabric. A good starting point for jersey fabric is:
- Upper thread tension: 2-3
- Lower thread tension: 3-4
- Stitch length: 2.5-3 mm
Tension Settings for Interlock Fabric
Interlock fabric requires a slightly higher tension setting than jersey fabric. This is because interlock fabric is thicker and more stable, allowing for a bit more thread to be fed through. A good starting point for interlock fabric is:
- Upper thread tension: 3-4
- Lower thread tension: 4-5
- Stitch length: 3-3.5 mm
Tension Settings for Ribbing Fabric
Ribbing fabric is highly stretchy and requires a lower tension setting to prevent the fabric from puckering or distorting. A good starting point for ribbing fabric is:
- Upper thread tension: 1.5-2.5
- Lower thread tension: 2.5-3.5
- Stitch length: 2-2.5 mm
Tension Settings for Spandex Fabric
Spandex fabric is highly elastic and requires a specialized tension setting. A good starting point for spandex fabric is:
- Upper thread tension: 1-2
- Lower thread tension: 2-3
- Stitch length: 1.5-2 mm
Additional Tips for Sewing Stretchy Fabric
In addition to using the right tension setting, there are several other tips to keep in mind when sewing stretchy fabric:
- Use a stretch needle: A stretch needle is designed specifically for sewing stretchy fabric and has a rounded point and a specialized eye.
- Use a walking foot or Teflon foot: A walking foot or Teflon foot can help guide the fabric smoothly and prevent it from bunching up or dragging.
- Use a longer stitch length: A longer stitch length can help prevent the fabric from puckering or distorting.
- Don’t pull the fabric: Allow the fabric to feed smoothly through the machine, don’t pull it. This can cause the fabric to distort or pucker.
Conclusion

What is the importance of choosing the right tension when sewing stretchy fabric?
Choosing the right tension is crucial when sewing stretchy fabric because it directly affects the quality and durability of the final product. If the tension is too tight, it can cause the fabric to pucker or distort, leading to an unflattering and uncomfortable garment. On the other hand, if the tension is too loose, it can result in a sloppy or baggy fit. By selecting the right tension, you can ensure that your stretchy fabric garment lies flat, moves smoothly, and retains its shape.
Moreover, the right tension also helps to prevent common issues like thread breakage, skipped stitches, and fabric stretching out of shape. When you use the correct tension, your sewing machine can move smoothly and efficiently, reducing the risk of errors and ensuring a professional-looking finish. By mastering the art of choosing the right tension, you can take your sewing skills to the next level and create beautiful, high-quality garments that will make you proud.
How do I determine the right tension for my stretchy fabric?
Determining the right tension for your stretchy fabric involves considering several factors, including the type of fabric, the weight of the fabric, and the intended use of the garment. For example, if you’re working with a lightweight, delicate fabric like spandex or lycra, you’ll want to use a lower tension to avoid distorting the fabric. On the other hand, if you’re working with a heavier, more robust fabric like cotton-lycra blend, you can use a slightly higher tension.
Another way to determine the right tension is to consult your sewing machine’s user manual or online resources. Many sewing machines come with pre-set tension settings for different types of fabrics, including stretchy fabrics. You can also experiment with different tension settings on a scrap piece of fabric to see what works best for your specific project. By taking the time to determine the right tension, you can ensure that your stretchy fabric garment turns out beautifully and professionally.
What are some common mistakes to avoid when sewing stretchy fabric?
One of the most common mistakes to avoid when sewing stretchy fabric is using the wrong needle size or type. Using a needle that’s too small or too large can cause the fabric to pucker or distort, leading to an unflattering finish. Another mistake is not using a walking foot or Teflon foot, which can help to guide the fabric smoothly and prevent bunching or dragging.
Another mistake to avoid is not using a stretch stitch or zigzag stitch, which can help to prevent thread breakage and ensure a flexible seam. Additionally, not pressing the seams as you go can cause the fabric to stretch out of shape, leading to a sloppy or baggy fit. By avoiding these common mistakes, you can ensure that your stretchy fabric garment turns out beautifully and professionally.
What is the difference between a stretch stitch and a zigzag stitch?
A stretch stitch and a zigzag stitch are both used for sewing stretchy fabrics, but they serve slightly different purposes. A stretch stitch is a specialized stitch that’s designed specifically for sewing stretchy fabrics like spandex, lycra, or knit fabrics. It’s typically a narrow, flexible stitch that allows for maximum stretch and recovery.
A zigzag stitch, on the other hand, is a more general-purpose stitch that can be used for a variety of fabrics, including stretchy fabrics. It’s typically a wider, more flexible stitch than a stretch stitch, and it’s often used for sewing seams that need to stretch in multiple directions. While both stitches can be used for sewing stretchy fabrics, a stretch stitch is generally preferred for garments that require maximum stretch and flexibility.
Can I use a serger to sew stretchy fabric?
A serger can be a great tool for sewing stretchy fabric, especially for finishing seams and preventing fraying. However, it’s not always the best choice for constructing garments from stretchy fabric. Sergers are designed to cut and finish seams as they sew, which can be problematic for stretchy fabrics that are prone to curling or distorting.
That being said, some sergers do come with specialized settings and attachments for sewing stretchy fabrics. If you have a serger with these features, you can use it to sew stretchy fabric with great results. However, it’s generally recommended to use a sewing machine with a stretch stitch or zigzag stitch for constructing garments from stretchy fabric, and reserve the serger for finishing seams and preventing fraying.
How do I prevent thread breakage when sewing stretchy fabric?
Preventing thread breakage when sewing stretchy fabric requires a combination of the right thread, needle, and tension. Using a high-quality thread that’s designed for sewing stretchy fabrics can help to reduce the risk of breakage.
