How to sew stretch fabric on a regular sewing machine
Sewing stretch or knit fabric doesn’t require a serger — with the right needle, stitch settings, and a few simple adjustments, your regular sewing machine can produce flexible, professional seams without skipped stitches or puckering.
Materials & settings needed
- Stretch or knit fabric
- Ballpoint or stretch needle (size 75/11 or 90/14)
- Matching thread
- Regular sewing machine
Step-by-step instructions
-
Use the right needle
Choose a ballpoint or stretch needle, which has a rounded tip that slides between the fabric fibres rather than piercing them. This prevents skipped stitches and avoids damaging the knit structure. Sizes 75/11 or 90/14 work well for most stretch fabrics — use the finer size for lighter knits and the larger for heavier ones.
-
Select the correct stitch
Use a narrow zigzag stitch or a dedicated stretch stitch if your machine has one. Set the zigzag width to around 1–1.5 — this allows the seam to stretch with the fabric rather than snapping the thread when the garment is worn or pulled.
-
Adjust the stitch length
Set a slightly longer stitch length of approximately 2.5–3 mm. A longer stitch reduces the number of needle penetrations per centimetre, which helps prevent the fabric from distorting or puckering along the seam as it goes through the machine.
Pro tip
Never pull or stretch the fabric as it feeds through the machine — let the feed dogs do the work naturally. Pulling causes the seam to stretch out of shape and is the most common reason for wavy, distorted seams on knit fabric. If your fabric is very slippery, try holding it gently with both hands just behind the presser foot to guide it without pulling.
