If you love sewing with knits or stretchy fabrics, you need to know about this stitch. This versatile stitch is one of the most underrated yet powerful features on your sewing machine perfect for creating durable, flexible seams that move with your fabric.
Whether you’re making a cozy t-shirt, hemming leggings, or finishing a neckline, this stitch ensures your seams won’t pop or break, no matter how much your fabric stretches.
Unlike a regular straight stitch, which can easily snap when pulled, the triple stretch stitch adds strength and elasticity by sewing each stitch three times forward, backward, and forward again. This clever technique reinforces your seams while allowing the fabric to stretch naturally, giving your handmade garments a polished, professional finish.
In this post, you’ll learn exactly what the triple stretch stitch is, why it’s essential for knit and stretch fabrics, and how to set it up correctly on your sewing machine for flawless results. We’ll also cover the best needles, thread types, and settings to use so you can achieve smooth, secure seams every time you sew.
Whether you’re a beginner exploring your sewing machine’s features or an experienced sewer looking to improve your finishes, this guide will show you why the triple stretch stitch deserves a permanent place in your sewing toolkit.

What Is a Triple Stretch Stitch?
The triple stretch stitch is a specialty stitch found on most modern sewing machines, especially models like the Baby Lock Soprano, Lyric, or Katherine.
On the Baby Lock Soprano, it’s stitch number five, and it’s designed for sewing stretchy fabrics such as jersey, spandex, and scuba.
Here’s how it works:
The machine sews one forward stitch, then two backward stitches over the same line before moving forward to the next stitch. This triple motion reinforces the seam and gives it amazing elasticity without compromising strength.
In simple terms, it’s like sewing each stitch three times for extra durability making it perfect for seams that need to stretch and recover.
Why You Should Use the Triple Stretch Stitch
If you’ve ever sewn with knits using a straight stitch, you’ve probably noticed what happens the seam breaks as soon as the fabric stretches. That’s because a straight stitch doesn’t have any give.
The triple stretch stitch, on the other hand, is built to move with your fabric. Here’s why you should use it:
- 🧵 Stretch and recovery: The stitch flexes with your fabric, preventing seams from snapping.
- 💪 Durability: The triple reinforcement creates a seam that’s strong and long-lasting.
- ✂️ Professional finish: It’s ideal for hems, necklines, cuffs, and sportswear.
- 💡 Beginner-friendly: It’s easy to sew and available on most domestic sewing machines.
How to Set Up the Triple Stretch Stitch on Your Sewing Machine
Let’s walk through how to set up and sew with the triple stretch stitch on your Baby Lock
1. Select the Right Stitch and Presser Foot
On the Baby Lock Soprano, the triple stretch stitch is stitch number 5.
Your machine screen will tell you which presser foot to use usually Foot J for this stitch.
If you’re using another model like the Baby Lock Lyric or Baby Lock Katherine, it should be similar.
2. Adjust Stitch Length and Foot Pressure
When sewing with knit fabrics, increase your stitch length slightly to prevent puckering.
If your stitch length is too short, your fabric may gather or ripple.
You can also adjust your presser foot pressure lower it to around “2” if your machine allows it. Less pressure helps your fabric feed evenly without stretching.
3. Choose the Right Thread and Needle
To get the best results with your stitch, use the right materials:
- Thread: Go for polyester thread it has more elasticity than cotton and moves with your fabric.
- Needle:
- Use a stretch needle for spandex or scuba fabric.
- Use a ballpoint needle for standard knit fabrics.
Both options are designed to prevent skipped stitches and damage to the fabric fibers.
4. Sew Slowly and Let the Machine Work
Once you start sewing, don’t pull or stretch the fabric.
Let your machine guide the fabric through at its own pace. Stretching the fabric as you sew can cause the seam to wave or distort.
Because the triple stretch stitch moves forward and backward, it takes a little longer than a standard stitch but the result is worth it! You’ll get a secure, flexible seam that holds up beautifully over time.
Triple Stretch Stitch vs. Straight Stitch: The Ultimate Test
To see why the triple stretch stitch is the clear winner, let’s compare it with a regular straight stitch.
- Triple Stretch Stitch Test:
When you stretch the fabric, the stitches stay intact. The seam stretches along with the material without breaking. - Straight Stitch Test:
Even with backstitching, a straight stitch can snap easily when the fabric stretches. That’s because it lacks the built-in flexibility of the triple stretch stitch.
The difference is obvious the triple stretch stitch creates a tougher, more flexible seam that won’t tear under stress. Perfect for leggings, t-shirts, or any stretchy project.
Common Uses for the Triple Stretch Stitch
You can use this stitch in a variety of sewing projects, including:
- 🩱 Sewing activewear or swimwear
- 👕 Finishing knit hems and cuffs
- 👖 Reinforcing seams in stretchy fabrics
- 👗 Creating garment necklines that won’t pop
It’s especially useful when you want your fabric to move and flex but still stay secure.
Troubleshooting Tips for the Triple Stretch Stitch
If your triple stretch stitch doesn’t look right or your fabric puckers, try these quick fixes:
- Increase your stitch length slightly.
- Reduce presser foot pressure.
- Use a stretch or ballpoint needle suited to your fabric.
- Avoid pulling or stretching the fabric as it feeds.
These small adjustments can make a big difference in achieving smooth, professional seams.
Final Thoughts: Why the Triple Stretch Stitch Deserves a Spot in Your Sewing Toolkit
The triple stretch stitch might take a little longer to sew than a regular straight stitch, but the results are worth it. It gives your stretchy garments the durability and flexibility they need to last.
Once you try it, you’ll never want to sew knits with a straight stitch again!
So next time you’re working with jersey, spandex, or any stretchy fabric remember to switch to this stitch. You’ll get stronger, smoother seams every time.
