Below are the most common causes and step-by-step fixes, arranged from simplest to most technical.

?? 1.

Needle Issues

Symptoms: Skipped stitches start suddenly or happen in specific spots.

? Fixes:

Replace the needle ? even if it looks fine. Knits dull needles fast.
Switch to a Stretch needle (Schmetz 75/11 or 90/14 Stretch) if using spandex, Lycra, or athletic knits.
Try a Ballpoint needle (Jersey) for cotton knits and interlocks.
Make sure the needle is fully inserted and tightened ? a loose needle is a silent culprit.

? 2.

Thread Problems

Symptoms: Thread breaks or skips intermittently, tension seems uneven.

? Fixes:

Use 100% polyester or all-purpose thread, not cotton.
If sewing very stretchy fabric (like swimwear), use wooly nylon or textured polyester in the bobbin or serger looper.
Re-thread the machine completely ? skipped stitches often mean the thread jumped out of a tension disc.
Check thread path for snags, burrs, or lint buildup.

?? 3.

Stitch Settings

Symptoms: Flat, tight, or uneven stitches that pop when stretched.

? Fixes:

Use a lightning bolt/stretch stitch or a narrow zigzag (width 0.5?1.0 mm, length 2.5?3 mm).
Avoid straight stitch unless using a stretch straight stitch (on some machines).
Slightly loosen upper tension (reduce by 0.5?1 setting).
Test on a fabric scrap ? if the seam pops, widen the zigzag or use a stretchier stitch.

? 4.

Fabric Handling

Symptoms: Fabric waves, stretches, or feeds unevenly.

? Fixes:

Use a walking foot or dual-feed foot to keep layers even.
Reduce presser foot pressure slightly (on many machines, a setting around ?2? instead of ?4? works better).
Don?t pull the fabric front or back ? let the feed dogs do the work.
Support fabric weight to prevent drag from the table edge.

? 5.

Stabilizing the Fabric

Symptoms: Thin or stretchy fabric gets ?chewed up? or shifts under the needle.

? Fixes:

Place a strip of wash-away stabilizer, tissue paper, or tear-away backing under the seam.
Use clear elastic or stay tape in seams like shoulders or necklines to stabilize stretch-prone areas.

? 6.

Machine Maintenance

Symptoms: Inconsistent stitches, skipping that seems random.

? Fixes:

Clean out lint from the bobbin area, feed dogs, and needle plate ? knits shed fibers fast.
Check for burrs or rough spots on the needle plate or hook. Polish lightly with fine sandpaper or replace the part.
Oil your machine (if recommended by manufacturer).
Have timing checked if the needle just barely misses the hook ? this can cause chronic skipped stitches.

? 7.

Advanced Solutions

If all else fails:

Try stretch thread in the top (e.g., Eloflex, Seraflex).
Use a serger or coverstitch machine if your project involves highly elastic fabrics.
Test sewing in a different direction (some knits stretch more crosswise than lengthwise).
