Tips for sewing knit fabric
Use the Right Needle and Stitch:
Knit fabrics require a specialized needle to prevent snagging and skipped stitches. Opt for a ballpoint or stretch needle, which has a rounded tip that slips between the knit fibers without causing damage. Additionally, use a stretch stitch or a narrow zigzag stitch on your sewing machine to accommodate the fabric's stretchiness while maintaining seam durability.
Stabilize Seams and Hems:
Knit fabrics have a tendency to stretch out of shape, especially along seams and hems. To prevent this, use stabilizing techniques such as clear elastic, knit interfacing, or stay tape along the seam allowances before stitching. This helps maintain the shape of the garment and prevents puckering or waviness.
Experiment with Tension and Stitch Length:
Adjusting the tension and stitch length on your sewing machine can make a big difference when sewing knit fabrics. Test different settings on a scrap piece of fabric to find the combination that works best for your particular fabric and machine. Generally, a slightly longer stitch length and lower tension help prevent stretching and distortion.
Use a Walking Foot or Teflon Foot:
A walking foot or Teflon foot can be incredibly helpful when sewing knit fabrics, as they help feed the fabric evenly through the machine and prevent stretching or shifting. If you don't have either of these specialty feet, you can also try placing tissue paper or a layer of water-soluble stabilizer under the fabric to help it glide smoothly.
Finish Seams Carefully:
Since knit fabrics don't fray like woven fabrics, you have more flexibility in how you finish seams. Consider using techniques like serging, overlocking, or a mock overlock stitch to neatly finish raw edges and prevent unraveling. Alternatively, you can use a double needle to create a professional-looking finish on hems and edges.
By following these tips, you'll be able to confidently tackle sewing projects using knit fabrics, whether you're making cozy sweaters, stretchy leggings, or comfy T-shirts. Remember to take your time, practice, and don't be afraid to experiment until you find the techniques that work best for you!
