Understanding the Differences between Woven and Knit Fabrics
Woven and knit fabrics are two commonly used types of materials in the world of sewing and fashion. While they may seem similar at first glance, there are some key differences that make understanding these distinctions crucial for achieving successful results in garment construction and pattern conversion.
One of the main differences between woven and knit fabrics lies in their construction. Woven fabrics are made by weaving or interlacing horizontal and vertical yarns together, creating a structured and stable fabric. On the other hand, knit fabrics are made by interlocking loops of yarn, resulting in a stretchy and flexible material.
Properties: Woven fabrics tend to be more durable and have less stretch than knit fabrics. They are generally stiffer and hold their shape better, making them ideal for structured garments such as blazers or button-down shirts. Knit fabrics, on the other hand, offer more stretch and drape, making them suitable for garments that require movement and comfort, such as t-shirts or leggings.
Pattern Conversion: When converting sewing patterns designed for woven fabrics to knit fabrics, it is important to consider the differences in stretch and drape. Knit fabrics require patterns with more ease and often benefit from adjustments in the fit to accommodate their stretch. Additionally, different sewing techniques may be required, such as using a zigzag stitch or twin needle to allow for the fabric’s stretch.
Understanding the differences between woven and knit fabrics is essential when it comes to garment construction and pattern conversion. By recognizing the unique properties of each fabric type, sewists can make informed decisions in selecting the appropriate material for their projects and successfully adapt patterns to suit the characteristics of knit fabrics.
Adapting the Seam Allowances for Knit Fabrics
When converting sewing patterns for woven fabric to knit fabric, one important consideration is how to adapt the seam allowances. Unlike woven fabrics, knit fabrics have stretch and require different construction techniques to ensure a comfortable and well-fitting garment.
Reducing Seam Allowances: One way to adapt the seam allowances for knit fabrics is to reduce them. While a standard 5/8-inch seam allowance is commonly used for woven fabrics, a smaller seam allowance of 1/4 inch or even 1/8 inch may be more suitable for knits. This smaller seam allowance allows for more stretch and movement in the fabric, resulting in a better fit.
Using Stretch Stitches: Another important aspect of adapting the seam allowances for knit fabrics is the type of stitch used. Instead of the traditional straight stitch used for woven fabrics, stretch stitches such as zigzag or serged stitches are recommended for knits. These stitches provide additional stretch and flexibility, preventing the seams from popping or breaking when the garment is worn.
Finishing the Seams: It is also important to consider how to finish the seams in knit fabrics. While woven fabrics often require seam finishing techniques such as serging or French seams, knit fabrics do not unravel as easily and may not require such extensive finishing. However, it is still recommended to finish the raw edges with either a zigzag stitch or an overlock stitch to prevent fraying and ensure the longevity of the garment.
Testing and Adjusting: As with any sewing project, it is important to test and adjust the seam allowances when working with knit fabrics. Different knit fabrics have varying levels of stretch, so it may be necessary to make adjustments to the seam allowances depending on the fabric’s properties. Before sewing the final garment, it is advisable to make a muslin or test garment using scrap fabric to ensure the fit and make any necessary adjustments to the seam allowances.
In summary, adapting the seam allowances for knit fabrics involves reducing the seam allowance size, using stretch stitches, considering the seam finishing techniques, and testing and adjusting as needed. By applying these techniques, sewists can successfully convert sewing patterns for woven fabric to knit fabric, resulting in comfortable and well-fitting garments.
Choosing the Right Type of Knit Fabric for Your Pattern

Here are some tips to help you adjust the fit when working with knit fabrics:
1. Take into account the stretch factor
Knit fabrics have varying degrees of stretch, so it’s important to choose a pattern size that accommodates the stretch factor of your fabric. If a pattern suggests using woven fabric, you might need to go down a size or two when using a knit fabric. It’s always a good idea to make a muslin or test garment first to check the fit before cutting into your final fabric.
2. Consider the drape of the fabric
Knit fabrics can have different levels of drape, which can affect how the garment hangs on your body. Take the drape into consideration when adjusting the fit. For example, if you’re working with a knit fabric that has a lot of drape, you might need to take in the side seams or add shaping to prevent the garment from looking too loose or baggy.
3. Opt for negative ease
In many cases, knit fabrics require a closer fit than woven fabrics. This is because the stretch of the fabric can provide the necessary ease. When adjusting the fit of a pattern for knit fabric, consider incorporating negative ease, which means making the garment slightly smaller than your actual measurements. This can help achieve a more fitted and flattering look.
4. Use appropriate finishing techniques
When working with knit fabrics, it’s important to choose appropriate finishing techniques to ensure the longevity and stretch of the garment. Consider using techniques such as a twin needle or serger for hemming, or using clear elastic in shoulder seams to prevent sagging.

Modifying darts: Darts are commonly used in sewing patterns to shape garments and create a tailored look. In knit fabrics, darts may not be necessary due to the fabric’s ability to stretch and conform to the body. Instead of traditional darts, you can consider using techniques such as gathering or ruching to achieve shaping in the knit fabric. These techniques allow for more flexibility and movement in the garment.
Modifying pleats: Pleats are another design element that may need modification when working with knit fabrics. Traditional pleats, which are created by folding and stitching fabric in place, can be challenging to achieve with the stretchy nature of knit fabrics. Instead, you can try using techniques like tucks or gathers to create soft, draping folds in the fabric. These techniques allow the knit fabric to maintain its stretch and drape while still achieving the desired pleated effect.
It is important to keep in mind that every sewing pattern and knit fabric is unique, so the modifications needed may vary. It is recommended to make a muslin or a test garment using the modified darts and pleats to ensure the desired fit and look. With practice and experimentation, you will become more comfortable modifying darts and pleats for knit fabrics and achieve stunning results in your garments.
Altering the Neckline and Collar for Knit Fabrics
When converting sewing patterns designed for woven fabrics to knit fabrics, it is important to consider the differences in stretch and drape. One area that often needs to be altered is the neckline and collar. The neckline in knit fabrics needs to accommodate the stretch and movement of the fabric, while still maintaining a professional and polished look.
To alter the neckline for knit fabrics, start by measuring the circumference of your neck and comparing it to the pattern’s neck opening. If the pattern’s neck opening is smaller than your neck circumference, you will need to widen it. This can be done by redrawing the neckline, adding a dart if necessary, or creating a new pattern piece for the neckline.
In terms of collar alterations, it is important to choose a collar style that works well with stretchy knit fabrics. Collars with a lot of structure, such as tailored collars, may not work as well as softer collar styles like shawl collars or standing collars. It is also important to consider the weight of the fabric and choose a collar style that won’t weigh down the garment or cause it to sag.
Suggested alterations for knit fabric necklines and collars:
- Widen the neckline if necessary to accommodate the stretch and movement of knit fabrics.
- Choose collar styles that work well with knit fabrics, such as shawl collars or standing collars.
- Avoid collar styles that are too structured and heavy, as they may weigh down the garment.
- Consider the drape and weight of the fabric when choosing a collar style.
By making these alterations to the neckline and collar, you can ensure that your garment fits and looks great in knit fabrics. Don’t forget to always test your alterations on a muslin or scrap fabric before cutting into your final fabric to ensure the best results.
Changing the Sleeve Design for Knit Fabrics
When converting sewing patterns designed for woven fabrics to knit fabrics, one important aspect to consider is the sleeve design. Knit fabrics have stretch and drape differently than woven fabrics, which can affect the fit and look of the sleeves. Here are some tips for changing the sleeve design for knit fabrics:
1. Choose a stretchy fabric
To ensure proper fit and comfort, it is important to choose a knit fabric that has good stretch and recovery. Opt for fabrics with a high percentage of stretch, such as jersey or interlock, as they will allow the sleeves to stretch and move with your body.

When working with a pattern designed for woven fabrics, you may need to make adjustments to the sleeve pattern to accommodate the stretch of the knit fabric. Start by measuring the circumference of your arm at the widest point and compare it to the pattern’s sleeve circumference. If there is a significant difference, you may need to make the sleeve wider or narrower to achieve the desired fit.
3. Consider the sleeve length
The stretchiness of knit fabrics can cause sleeves to stretch out over time, which may result in a longer sleeve length than desired. To prevent this, consider shortening the sleeve pattern slightly when working with knit fabrics. You can also experiment with different sleeve lengths, such as three-quarter or cap sleeves, to take advantage of the drape and stretch of knit fabrics.
Overall, changing the sleeve design for knit fabrics involves choosing the right fabric, adjusting the pattern, and considering the sleeve length. By taking these factors into account, you can ensure that your sleeves fit and drape beautifully in knit garments.
Adding Elastic or Ribbing to the Waistband for Knit Fabrics
When converting a sewing pattern for woven fabric to knit fabric, one of the key adjustments you may need to make is to the waistband. Knit fabrics have more stretch and require a different approach to ensure a comfortable and secure fit. There are two common methods for adding an elastic or ribbing waistband to knit fabrics.
Method 1: Elastic Waistband
One option is to add an elastic waistband to the garment. Start by measuring the circumference of your natural waist and cut a piece of elastic to that length. Next, fold the waistband of your garment over, leaving a small seam allowance, and sew it in place, creating a casing for the elastic. Using a safety pin or bodkin, thread the elastic through the casing, making sure it is evenly distributed. Overlap the ends of the elastic and sew them together securely. Finally, stitch the casing closed, being careful not to catch the elastic in the seam.
Method 2: Ribbing Waistband
If you prefer a more tailored and refined look, you can use ribbing to create a waistband for your knit garment. Ribbing is a stretchy fabric typically used for cuffs, collars, and waistbands. Cut a piece of ribbing fabric with a circumference that matches your natural waist measurement. Sew the short ends of the ribbing together to form a loop. Fold the ribbing in half lengthwise, wrong sides together, and press it. Align the raw edges of the ribbing with the waistline of your garment, making sure it is evenly distributed. Stretch the ribbing slightly as you sew it in place, using a stretch stitch or a twin needle for added durability. Trim any excess fabric and press the waistband seam towards the garment.
By incorporating an elastic or ribbing waistband into your knit garment, you can ensure a comfortable and secure fit that is suited for the stretchiness of the fabric. Experiment with different methods and techniques to find the one that works best for your project and personal preference.
Replacing Zippers and Buttons with Stretch Closures for Knit Fabrics
The choice of closures in sewing projects can greatly affect the comfort and fit of the final garment, especially when it comes to working with knit fabrics. While zippers and buttons are commonly used closures in woven fabric garments, they may not be the best options for knits. Knit fabrics have stretch and give, and using rigid closures like zippers and buttons can restrict movement and create discomfort.
To address this issue, it is recommended to replace zippers and buttons with stretch closures when sewing with knit fabrics. Stretch closures, such as elastic or stretchy ribbons, allow the garment to stretch and move with the body, ensuring a more comfortable and flexible fit. Additionally, stretch closures are easier to sew onto knit fabrics as they can be stretched along with the fabric during the sewing process.
Replacing Zippers
- When replacing zippers with stretch closures in knit garments, consider using an elastic waistband or drawstring instead. These options provide flexibility and stretch, allowing the waistband to move with the body.
- Another option is to use a stretchy ribbon or elastic to create a faux-placket closure. This gives the appearance of a buttoned or zippered closure without the rigidity, allowing for more comfort and freedom of movement.
Replacing Buttons
- Instead of using buttons on knit garments, consider using snap fasteners or hook and loop closures. These closures provide a secure hold while still allowing for stretch and movement in the fabric.
- An alternative option is to use stretchy loops or ties as closures. These can be sewn onto the garment and stretched to fasten the garment securely without restricting movement.
When working with knit fabrics, it is important to choose closures that complement the fabric’s stretch and flexibility. By replacing zippers and buttons with stretch closures, you can ensure that your knit garments are comfortable, functional, and allow for ease of movement.
Adjusting the Hems for Knit Fabrics
Knit fabrics have a unique stretch and drape that require adjustments when it comes to hemming. Unlike woven fabrics, knit fabrics do not have the same stability and structure, which can cause hems to stretch out or become distorted. To ensure a professional finish, it is important to make the necessary adjustments when working with knit fabrics.
1. Consider the type of knit fabric
There are different types of knit fabrics, each with its own characteristics. Some knits, like jersey or interlock, have a moderate stretch, while others, like rib knit or sweater knit, have a higher stretch and are more prone to sagging. Take into account the stretch and recovery of the fabric when deciding on the hem width and type of finish.
2. Use a stretch stitch or serger
To prevent the hem from popping or snapping when the fabric is stretched, use a stretch stitch or a serger. A stretch stitch, such as a zigzag or a twin needle stitch, allows the hem to stretch along with the fabric, preventing it from becoming distorted. If you have a serger, you can also use a rolled hem for a clean and stretchy finish.
3. Test the hem before finalizing
Before sewing the final hem, it is always a good idea to test the fabric by stretching it in different directions. This will give you an idea of how the fabric will behave and allow you to make any necessary adjustments. If the hem feels too tight or too loose, adjust the width accordingly. Remember that the hem should be able to stretch without distorting the fabric.
4. Consider using a stabilizing tape
If you are working with a particularly unstable knit fabric, you may want to consider using a stabilizing tape. This can be applied to the edge of the fabric before hemming to add stability and prevent stretching. Simply sew the tape along the hemline, and then fold and stitch the hem as usual.
By making these adjustments, you can ensure a professional-looking finish when hemming knit fabrics. Remember to take into account the fabric’s stretch and recovery, use the appropriate stitch or serger, test the hem before finalizing, and consider using a stabilizing tape if needed. With these tips, you can achieve beautiful hems that will not stretch out or distort over time.
Working with Knit Fabric Patterns that Require Lining
When working with knit fabric patterns that require lining, there are a few key considerations to keep in mind. Knit fabrics have a stretchy nature that can complicate the lining process, but with the right techniques, you can achieve a professional look and fit.
One important thing to remember when working with knit fabric patterns is to choose a lining fabric that has a similar amount of stretch. This will help maintain the flexibility and drape of the garment. Stretchy lining fabrics, such as stretch satin or stretch mesh, are great options to consider.
Additionally, it’s important to adjust the pattern to accommodate the stretch of the fabric. This can be done by adding ease to the lining pattern pieces or using a stretch stitch when sewing the lining seams. It’s also helpful to baste the lining to the outer fabric before permanently sewing them together, to ensure the lining stretches and moves with the garment.
Another technique to consider when working with knit fabric patterns that require lining is using a facing instead of a full lining. A facing is a strip of fabric that is sewn to the inside of the garment at the neckline, armholes, or hem, providing a clean finish. This eliminates the need for a separate lining fabric and allows for more flexibility and comfort.
Overall, working with knit fabric patterns that require lining requires attention to detail and understanding of the unique properties of knit fabrics. By choosing the right lining fabric, adjusting the pattern for stretch, and considering alternative techniques like facings, you can successfully create lined knit garments that are both comfortable and stylish.
