The zigzag stitch is one of the most versatile and essential stitches in both home sewing and industrial applications. If you own a sewing machine, chances are it’s equipped with a zigzag setting. While the straight stitch is the bread and butter of sewing, the zigzag stitch is your multitool—strong, flexible, and adaptable to many fabrics and functions.
What Is a Zigzag Stitch?
A zigzag stitch is a back-and-forth stitch pattern that forms a zigzag shape rather than a straight line. The needle moves from left to right in a rhythmic motion, forming angles instead of linear stitches. You can adjust the width (how far the needle swings) and length (distance between the points of each “zigzag”) depending on your fabric and the purpose of the stitch.
Where Is Zigzag Stitch Used?
1. Preventing Fraying
Zigzag stitching is commonly used to finish raw edges. Unlike straight stitches, which can unravel easily, the zigzag stitch binds the edge, reducing fraying.
2. Stretch Fabrics
Zigzag stitches stretch with the fabric, making them ideal for knits, jerseys, and other stretchy materials. A straight stitch would snap when the fabric stretches—zigzag allows for movement.
3. Sewing Elastic
It’s the go-to stitch for attaching elastic bands in waistbands, underwear, or swimwear. The flexibility of the stitch accommodates the stretch of the elastic.
4. Decorative Stitching
With adjustments to width and length, a zigzag stitch can serve a decorative function, adding texture or patterns to your sewing project.
5. Buttonholes and Patching
Zigzag is the backbone of buttonhole stitching and reinforcement patches. It creates dense stitches in a confined space, adding strength.
6. Appliqué
It helps attach fabric pieces to a base layer by encasing the edges in tight zigzags, securing them cleanly and preventing fraying.
How to Do a Zigzag Stitch
Tools You’ll Need:
-
A sewing machine with a zigzag setting (most modern machines have this)
-
The correct needle for your fabric type
-
Matching or contrasting thread
-
Fabric for your project
-
Scrap fabric for testing
Step-by-Step Instructions:
1. Select the Zigzag Setting
Look at your machine’s stitch selector. Choose the zigzag option—usually represented by a jagged line. Basic machines may have a fixed width and length; more advanced machines let you control both.
2. Adjust the Stitch Width and Length
-
Width: This controls how far the needle swings side to side. Wider widths are good for decorative or edge-finishing work.
-
Length: This controls the spacing between each zigzag point. Shorter lengths give denser, stronger stitching.
Tip: For stretch fabrics, try a medium width and short length to retain flexibility.
3. Thread Your Machine
Make sure your bobbin and top thread are properly wound and threaded. Always pull both threads to the back before you start sewing.
4. Test on Scrap Fabric
Before stitching your actual piece, test your settings on a similar fabric scrap. Adjust as needed for tension, width, and length.
5. Start Sewing
Place the fabric under the presser foot and lower it. Sew slowly at first to make sure the needle isn’t striking the presser foot or plate (which can happen with wider zigzags). Guide the fabric gently—don’t pull.
6. Secure the Stitch
At the beginning and end of the seam, backstitch slightly to lock the thread in place. This prevents unraveling.
7. Trim Excess Threads
Use scissors or a thread cutter to clean up your ends once the stitching is complete.
Tips for Better Zigzag Stitching
-
Use the right needle: Stretch or ballpoint needles for knits, universal or sharp needles for woven fabrics.
-
Stabilize thin fabric: Use a stabilizer or interfacing to keep delicate fabrics from puckering.
-
Don’t pull the fabric: Let the feed dogs do the work, or your stitch could distort.
-
Experiment with decorative effects: Play with stitch length and width to create unique finishes.
Common Zigzag Stitch Settings (General Guidelines):
| Purpose | Stitch Width | Stitch Length |
|---|---|---|
| Seam stretch fabric | 2.5 – 4 mm | 1 – 2 mm |
| Finish raw edges | 3 – 5 mm | 1.5 – 2.5 mm |
| Attach elastic | 3 – 4 mm | 1 – 1.5 mm |
| Decorative stitch | 4 – 6 mm | 2.5 – 4 mm |
Final Thoughts
Whether you’re hemming a pair of yoga pants, sewing on a patch, or adding flair to a plain fabric, the zigzag stitch is a workhorse. It’s reliable, adaptable, and a fundamental part of any sewer’s skillset. Master it, and you open the door to more creative and durable sewing projects.
