How to Stop Knit Fabric from Curling: Expert Tips

To stop knit fabric from curling, stabilize the edges with starch or fusible interfacing. Sewing a row of stay stitches along the edges can also prevent curling.

Working with knit fabrics can often lead to frustration when the edges curl, making it difficult to sew or finish a garment. This common nuisance can detract from the neatness of your sewing project, but luckily, there are practical solutions that can be easily implemented.

Whether you’re a beginner or an experienced seamstress, understanding how to keep those pesky curls at bay is essential for a professional-looking outcome. Grasping these techniques will save time and improve the quality of your knit fabric projects, ensuring that your finished work lies flat and looks polished. Let’s dive into some effective methods to tame your knit fabric and keep curling edges from ruining your sewing experience.

Introduction To Knit Fabric

Knit fabric is prized for its stretchiness, comfort, and versatility, but one common challenge faced by sewing enthusiasts and garment manufacturers alike is its tendency to curl at the edges. This characteristic can be attributed to the way knit fabric is produced, with interlocking loops of yarn that can lead to uneven tension on the fabric’s edges once cut. This curling can complicate the sewing process, making it difficult to achieve clean, professional-looking hems and seams.

To manage this issue, a variety of techniques and stabilizers are utilized to prevent the fabric from curling during the sewing process. Employing these methods can result in smoother edges, which will not only enhance the appearance of the finished product but also improve the ease of construction. It is imperative for anyone working with knit fabrics to learn these strategies in order to produce high-quality garments and items.

Prevention Techniques

Choosing the right knit fabric can significantly reduce the tendency to curl. Opt for fabrics with a tighter weave or blended fibers, as these are less prone to curling. Fabrics like rib knits, interlock knits, and double knits have more structure and can help maintain a flat shape.

Proper handling and storage play a crucial role in keeping knit fabrics from curling. Always lay fabric flat and avoid hanging or stretching, which can distort the natural lay of the fibers. Rolling the fabric rather than folding it can also prevent creases that may promote curling edges.

Integrating stabilizers is a practical approach to protect fabric edges from curling. Edge-stabilizing products, fusible tapes, or starch can be applied to the fabric edges. These materials add rigidity to the edges, effectively minimizing the curl and simplifying the handling process for sewing projects.

Expert Tips For Working With Knit Fabrics

Selecting the appropriate needles and threads is crucial for preventing knit fabric from curling. Opt for ballpoint needles which are specifically designed for knit fabrics; these reduce the likelihood of snags and runs. Thread choice also plays a significant role—synthetic threads tend to be more flexible, making them a better match for the stretchy nature of knit fabrics.

Adjusting sewing machine tension and choosing the right stitch type is vital to maintain the fabric’s structure. A balanced tension prevents puckering, ensuring a flat seam. Use a small zigzag stitch to allow the fabric to stretch without breaking the seams. This stitch mirrors the natural give of knit fabrics, providing a professional finish.

For blocking knitted projects, a technique to reduce curling, dampen the fabric and shape it to the desired dimensions on a flat surface. Use rust-proof pins to hold the fabric in place, letting it dry completely. This process helps relax the fibers and sets the project to maintain its shape.

Post-construction Solutions

Steam blocking is an effective technique to relax and reshape knit fabric post-construction. This method involves gently steaming and pinning the fabric to a flat surface, allowing it to cool and set without the original curl.

Hemming and edge finishes are also vital to prevent the edges from rolling. Techniques like adding a stretch stitch or knit binding can significantly improve the fabric’s stability. These finishes can be both functional and decorative, offering an opportunity to add a personal touch while solving the curling issue.

Applying fabric sprays or anti-curling products can also provide a quick solution to combat fabric curling. These products are formulated to stiffen the edges slightly, helping them to lay flat. It’s important to follow the manufacturer’s instructions and test the product on a small area first to ensure compatibility with the fabric.

Advanced Techniques And Considerations

Incorporating borders or bands is a highly effective strategy to prevent the edges of knit fabric from curling. By attaching a non-curling border, such as a woven fabric or a rib knit with substantial stretch recovery, you can ensure that the edges remain flat. Work the border in a contrasting or complementary color for an additional design element. This method requires precise measurement and even stitching to maintain a consistent appearance.

Employing double-stitch techniques reinforces the edges and significantly reduces the tendency of knit fabric to curl. Techniques such as backstitching at the beginning and end of seams or using a two-needle approach can add the necessary structure to your project. Accuracy during execution of these techniques is crucial and may require some practice to perfect.

Blending in synthetic fibers, such as polyester or nylon, with natural yarns can greatly improve knit fabric’s structure and reduce edge curling. Synthetic fibers are typically more resilient and hold their shape better than natural fibers. This blend creates a fabric that combines the best attributes of both fiber types, resulting in a material that is less prone to curling yet still comfortable to wear. When selecting a blend, consider the end use of the fabric to ensure the appropriate balance of characteristics.

Summary And Best Practices

Preventing knit fabric from curling is a common challenge faced by knitters and sewists. Stabilizing the edges through various techniques is crucial. Blocking is one effective method; gently washing the finished project and laying it flat to dry can significantly reduce curling. Using starch sprays or fabric stabilizers can also provide temporary rigidity. Applying edge stitches like moss or seed stitch create a natural border that resists curling. Considering the material, cotton and synthetic fibers are less likely to curl compared to wool.

  • Block your finished projects to shape and set the fabric.
  • Choose the right edge stitches such as garter, ribbing, or seed stitch.
  • Spray with starch or stabilizer for additional support.
  • Test fabric samples with different techniques to determine the best approach for your material.

Personal experimentation is key; combine techniques or develop unique solutions that work best for your fabric. By referencing this checklist and continuously practicing, you will discover the most effective means to keep your knit fabrics flat and curl-free.


Preventing your knit fabric from curling is simple with these methods. With proper stabilization, moisture control, and careful handling, your knitting projects can maintain their shape beautifully. Remember, practice makes perfect—so keep experimenting and enjoy the process. Happy knitting!
