Why Is My Sewing Machine Skipping Stitches on Stretch Fabric?
A stretch needle’s scarf—the indentation above the eye—is cut deeper than a universal needle’s, creating a larger thread loop that gives the machine’s hook more time to catch it before the elastic knit fabric snaps back. This timing difference is the entire reason stretch fabric causes skipping with standard needles.
When stitches skip on jersey or Lycra, the problem is almost always the needle type, not the tension. Understanding this mechanism helps you fix it quickly without unnecessary adjustments.
How Stitch Skipping Happens with Knit Fabrics
A stitch forms when the machine’s hook catches the top thread loop as the needle rises. With woven fabrics, the needle pierces cleanly through thread intersections, and the loop forms predictably. But knit fabrics behave differently—their elastic fibres deflect away from a sharp needle point rather than being cleanly pierced.
📺 Watch: Skipping Stitches on Stretch Fabrics
A universal needle’s sharp point can push the knit fabric down into the hook opening, distorting the thread loop’s formation. The hook then misses the loop, resulting in skipped stitches. A ballpoint or jersey needle (paid link)See on Amazon helps reduce fabric disruption by sliding between the knit loops instead of forcing through them. Stretch needles are designed for highly elastic fabrics where even a standard jersey needle might struggle.
Choosing the Right Needle for Your Fabric
For most jersey fabrics like T-shirts and dresses, a ballpoint or jersey needle prevents skipped stitches and reduces snagging. It slides between fibres without damaging them.
For high-elasticity materials like leggings, swimwear, or anything with significant Lycra content, a stretch needle is necessary. Schmetz Stretch Needles (paid link) are engineered specifically for these challenging fabrics.

If you install a stretch needle and skipping continues, the issue likely lies elsewhere. Check the thread path thoroughly—rethread with the presser foot raised, ensure the bobbin is seated correctly, and clean any lint from the bobbin area before considering tension adjustments.
Supporting Tools and Techniques
While the needle is the primary solution, other elements contribute to successful stretch fabric sewing.
A knit foot helps reduce stretching, puckering, and distortion by feeding the fabric evenly from top and bottom. Pair it with the correct needle for optimal results.
Stitch choice is equally important. Straight stitches will break when the garment stretches. Use a narrow zig-zag or dedicated stretch stitch instead. Many machines have a stretch stitch setting—consult your manual for specific instructions.
Sewing too quickly on stretch fabrics can also cause skipping. A moderate pace gives the needle time to complete its movement properly, especially on thicker knits like sweatshirting.
Systematic Troubleshooting Approach
Follow this sequence for efficient problem-solving—simple checks first, adjustments last.
Rethread completely with the presser foot raised. This ensures the thread seats properly between the tension discs, which is crucial for consistent loop formation.
Install a new needle of the correct type. Use jersey needles for ordinary knits, stretch needles for elastic fabrics. Match the size to your fabric weight—an unsuitable size can cause breakage or visible holes. Replace needles after several projects as blunt needles skip.
Check the bobbin area. Remove the bobbin, clear any lint, and reinsert it according to your manual’s instructions. Incorrect bobbin loading causes skipping regardless of other factors.
Clean thoroughly. Brush lint from the feed dogs and hook area. Lint buildup from lower-quality thread can disrupt tension and cause snags.
Adjust upper tension as a last resort. Make small, documented changes. Bobbin tension adjustments rarely fix skipping and may complicate matters.

If the needle strikes the plate, the hook shows damage, or skipping occurs on all fabrics after these steps, professional service may be needed.
Product Focus: Schmetz Stretch Needles
For elastic knits, leggings, swimwear, and Lycra blends, Schmetz Stretch Needles (paid link) provide specialised performance. They’re engineered to handle the deflection characteristics of highly elastic fabrics that cause skipping with standard needles.
While stretch needles excel with challenging materials, they’re not necessary for every knit. Ordinary jersey fabrics work well with standard jersey needles, which are slightly more economical. Schmetz offers both types for different applications.
Budget alternatives like Anvin Universal Needles exist, but for consistent results with elastic fabrics, the precision of Schmetz Stretch needles proves more reliable.
Needle Selection Guide
| Fabric Type | Needle Type | Best For |
|---|---|---|
| Ordinary Jersey | Ballpoint / Jersey | T-shirts, dresses, children’s clothes |
| High-Elasticity (Lycra) | Stretch | Leggings, swimwear |
| Heavyweight Knits | Stretch | Sweatshirting |
| Fine Knits | Jersey | Lightweight jerseys |
| Woven Fabrics | Universal | Non-stretch materials only |
Common Questions Answered
Can I use a universal needle on stretch fabric?
While possible, universal needles often cause skipped stitches and fabric snagging on stretch materials. Ballpoint or stretch needles are specifically designed to slide between knit fibres rather than piercing them, preventing these issues.
Why are my stitches skipping on the bottom of the fabric?
Skipping on the underside typically indicates bobbin-related issues. Check that the bobbin is inserted correctly, clear any lint from the bobbin area, and verify you’re using the correct bobbin type for your machine model.
Does needle size matter for stretch fabric?
Absolutely. Match needle size to fabric weight for best results. Most medium-weight jersey works well with a 75/11 needle, while heavier sweatshirt knit needs 90/14. Consult the size chart on the needle packet for specific guidance.
The triple zig-zag stitch eliminates skipping on the most problematic stretch fabrics even when the correct needle is fitted, by creating multiple connection points that withstand extreme stretching.
