Sewing with Knit Fabric: Tips and Techniques

Knit fabric can be intimidating for many beginners. Its stretchy nature and tendency to curl can make it challenging to sew with. However, with the right techniques and tools, sewing with knit fabric can be a breeze. In this comprehensive guide, we will cover everything you need to know about sewing with knit fabric – from choosing the right needle to finishing seams.

Types of Knit Fabric

Before diving into how to sew knit fabric, let’s first understand the different types of knit fabric. There are three main types of knit fabrics: single knit, double knit, and stretch jersey.

– Single Knit: This is the most common type of knit fabric that has a smooth surface on one side and a textured surface on the other side. It has good drape and is used for making t-shirts, leggings, and dresses.
– Double Knit: This type of fabric is thicker and more stable than single knits as it is made by knitting two layers together. It has less stretch than single knits and is commonly used for making skirts, pants, and jackets.
– Stretch Jersey: This is a lightweight and stretchy fabric often made from cotton or synthetic fibers. It’s commonly used for making activewear, swimwear, and undergarments.

Tips for Sewing Knit Fabric

Here are some essential tips to keep in mind while sewing with knit fabric:

– Choose the Right Needle: Using the correct needle is crucial when sewing with knits. A ballpoint or stretch needle is recommended as they have rounded tips that push through the fibers instead of piercing them.
– Use a Walking Foot: A walking foot evenly feeds your fabric through the machine without stretching it, making it an excellent tool for sewing knits.
– Adjust Your Tension: Knit fabric is stretchy, so it’s important to adjust your machine’s tension to prevent puckering or stretched stitches. Test on a scrap piece of fabric first before starting on your project.
– Use a Narrow Zigzag Stitch: A narrow zigzag stitch allows the fabric to stretch without breaking the stitches. Set your stitch length between 1-2mm and width between 1-2.5mm.
– Use Washaway Stabilizer: If you’re using a lightweight or slippery knit, place washway stabilizer under the fabric while sewing to prevent it from slipping and puckering.

Sewing Techniques for Knit Fabric

Now that we have covered some essential tips let’s dive into some sewing techniques for knit fabric.

– Cutting the Fabric: When cutting knit fabric, always use sharp scissors to ensure clean cuts without snagging or pulling on the fabric. It’s also recommended to use pattern weights instead of pins as they can leave holes and distort the fabric.
– Sewing Seams: Sewing seams in knit fabric can be challenging because of its stretchiness. Start by pinning or using clips along the seamline to prevent shifting. Sew with a narrow zigzag stitch, stretching the fabric slightly as you go. For a more professional finish, use a serger or overlocker.
– Finishing Seams: Standard seam finishes like zigzag stitches or overcastting can look bulky on knit fabrics. Instead, opt for flat-felled seams or mock serged seams for a clean and neat finish.
– Hemming Knit Fabric: To hem knit fabric, use a twin needle to create two parallel rows of straight stitches on the right side of your garment while catching the raw edge on the wrong side. This creates a stretchy and professional-looking hem. Alternatively, you can use a coverstitch machine if you have one.
– Adding Elastic: If your knit project requires elastic, use clear or cotton elastic instead of traditional elastic as it has more stretch and is less likely to snap or break.

Troubleshooting Common Issues

Despite following all the tips and techniques, you may still encounter some issues while sewing with knit fabric. Here are some common issues and how to troubleshoot them:

– Puckering: Puckering occurs when the fabric is stretched while being sewn. Adjust your tension settings and try using a tissue paper or stabilizer underneath the fabric while sewing.
– Skipping Stitches: Skipping stitches can happen when using the wrong needle or not using enough tension. Try using a ballpoint or stretch needle and double-check your tension settings.
– Fabric Curling: Sometimes, knit fabrics tend to curl at the edges, making it challenging to sew straight seams. Try cutting the fabric with a rotary cutter instead of scissors as it helps keep the edges straight.
– Bunching Up at Seams: If your fabric bunches up at

Sewing knit fabric can seem intimidating for beginners, but with the right techniques and tools, it can be an enjoyable and satisfying experience. Knit fabrics are versatile and popular due to their stretch and comfort, making them a go-to choice for many clothing items such as t-shirts, leggings, and dresses. In this comprehensive guide, we will cover everything you need to know about sewing knit fabric, from choosing the right materials to mastering various stitches and finishing techniques. So whether you’re brand new to sewing or looking to expand your skills, read on to learn how to sew with knit fabric like a pro.

Understanding Knit Fabrics

Before diving into the sewing process, it’s essential to understand what makes knit fabrics unique. Unlike woven fabrics that are made by weaving vertical and horizontal yarns together, knits have interlocking loops of yarn that give them their stretch. Knit fabrics come in a variety of types such as jersey, interlock, rib knits, sweater knits, and more. Each type has its characteristics that affect how they feel and behave when being sewn. For instance, jersey knits are smooth and have excellent stretch recovery while rib knits have ridges that give them more texture.

Choosing the Right Materials

When it comes to sewing with knit fabric, choosing the right materials is crucial. Using the wrong materials can result in a poorly made garment that won’t last long or fit correctly. Here’s a breakdown of the materials you’ll need when sewing with knit fabric:

Fabric: As mentioned earlier, there are several types of knit fabric available in stores. When selecting your fabric, consider the garment’s purpose and your preference for stretchiness. Also, keep in mind that some varieties of knit fabrics may require special needles or stitches.

Threads: For sewing knit fabric, polyester or polyester-wrapped cotton threads are highly recommended. They have the right amount of stretch and strength to withstand the pressure of stretchy fabrics.

Needles: Regular sewing machine needles can work on most knit fabrics, but ballpoint or stretch needles are better choices as they’re specially designed for knit fabric. They have rounded points that prevent them from snagging and piercing through the fabric’s loops.

Elastic: Depending on your project, you may need elastic to add structure and shape to your garment. Elastic comes in various widths and finishes, such as clear or ribbed.

Cutting and Preparing Knit Fabric

Before cutting your fabric, it’s crucial to prewash and dry it to avoid any shrinkage after the garment is completed. Knit fabrics tend to shrink more than woven fabrics, so be sure to wash them in warm water and tumble dry on low heat. Once prewashed, avoid ironing your knit fabric unless necessary; instead, use a fabric steamer.

When laying out your pattern pieces on the fabric, ensure that the direction of the stretch aligns with the direction indicated on the pattern. This will ensure that your garment will fit comfortably without losing its shape.

Sewing Techniques

Now that you have all your materials ready let’s get started with sewing! Here are some essential techniques for sewing with knit fabric:

Seam Finishing: One of the best ways to finish a seam on knit fabrics is by using a serger. Sergers create a professional-looking finish by trimming excess seam allowance and locking stitches in one step. If you don’t have a serger, consider using a narrow zigzag stitch or overlock stitch on your regular sewing machine.

Hemming: Unlike woven fabrics where you can fold hems under twice for a neat finish, knit fabrics require different methods for hemming. For instance, rolled hems work well for lighter weight knits, while twin needles create a double-row of stitches that prevent stretching on heavier fabrics.

Stitches: When it comes to stitches, there are endless possibilities for sewing with knit fabric. The most commonly used are the straight stitch, zigzag stitch, and stretch stitch. Straight stitches are great for seams on stable knits, whereas zigzag or stretch stitches work best on stretchier fabrics.

Tips and Tricks for Sewing Knit Fabric

Now that you have the basics down let’s go over some tips and tricks that will make sewing knit fabric easier:

– Use your fingers to guide the fabric rather than pulling or pushing it through the machine.
– Always start and end sewing a seam with backstitching to secure the threads.
– Use tissue paper or stabilizer under thin or slippery knit fabrics to prevent them from getting sucked into the machine.
– If your machine has adjustable presser foot pressure, reduce it when sewing knits to avoid distortion.
– Test your stitches on scrap fabric before starting on your project to ensure they’re not too tight or too loose.
– Keep your sewing area clean;
