Running Stitch vs. Backstitch: Speed vs. Strength
When you pick up a needle and thread, you have two primary options: do you want to finish quickly, or do you want the seam to last forever?
The Running Stitch and the Backstitch are the yin and yang of hand sewing. One is the “sprinter”—light, fast, and agile. The other is the “weightlifter”—slow, dense, and incredibly strong. Mastering both is the hallmark of a skilled sewist.
The Running Stitch is a simple “up-and-down” weaving motion. It is fast, uses less thread, but is weak and leaves gaps between stitches.
The Backstitch involves doubling back on every stitch, creating a solid, continuous line. It is the strongest hand stitch, mimicking a machine lockstitch, but consumes 2x the thread and time.
1. The Structural Anatomy
To understand why the backstitch is stronger, you have to look at how the thread interacts with the fabric.
Running Stitch
Thread weaves In & Out.
Result: 50% Coverage.
Backstitch
Thread overlaps backwards.
Result: 100% Coverage.
2. The Running Stitch: “The Baster”
The running stitch is the first stitch children learn. It is intuitive: push the needle in, pull it out, move forward.
✅ Best Used For:
- Basting: Temporary holding stitches.
- Gathering: Pulling the thread to ruffle fabric.
- Sashiko/Embroidery: Decorative patterns where the gaps are part of the design.
- Low-Stress Seams: Hems on light scarves.
⚠️ Weaknesses:
If you pull the thread, the fabric bunches up (gathers). If the thread breaks at any point, the entire seam can unzip instantly.
3. The Backstitch: “The Anchor”
The backstitch gets its name from its motion. You bring the needle up, move backward to the end of the previous stitch, go down, and then travel forward two spaces underneath the fabric.
✅ Best Used For:
- Structural Seams: Fixing ripped pants or sewing garments by hand.
- Zippers: Installing zippers where machines can’t reach.
- Attaching Straps: High-stress areas that carry weight.
⚠️ Weaknesses:
It is slow. It uses twice as much thread as a running stitch. It is also very difficult to remove (rip out) if you make a mistake.
4. Tools of the Trade
Because these stitches serve different purposes, they benefit from different tools.
For the Backstitch (Strength)
Backstitching through multiple layers of heavy fabric (like denim repair) requires force. You need a thimble to push the needle without injuring your finger.
Clover Natural Fit Leather Thimble
Unlike rigid metal thimbles, leather molds to your finger. This is essential for backstitching, where you need to feel the needle to guide it backward precisely into the previous hole.

Running stitches are often used for Sashiko or quilting, where you load multiple stitches onto the needle at once. This requires a long, sharp needle.
Clover Sashiko Needles (Long)
These extra-long needles allow you to “stack” 4 or 5 running stitches before pulling the thread through. This doubles your speed when doing decorative work or basting.

Many projects require both.
- Step 1: Use a Running Stitch (or clips) to temporarily hold the fabric layers together (Basting).
- Step 2: Use a Backstitch to permanently sew the seam.
- Step 3: Remove the running stitch.
Conclusion
If you need speed or are checking the fit of a garment, the Running Stitch is your friend. If you need a seam to survive the washing machine or a day at work, trust the Backstitch.
Are you repairing a ripped seam? Don’t waste time with a running stitch—it will just pop again. Go straight for the backstitch. For more repair tips, check out our Troubleshooting Guide.
