In the world of DIY sewing and slow fashion, every stitch counts. One technique that can elevate your handmade garments is understitching. At Sewpronto, we believe in crafting pieces that not only reflect your personal style but also embody quality and sustainability. Understanding what understitching is and how to apply it can significantly enhance the finish of your garments, making them look more professional and polished.
Understanding Understitching
Understitching is a sewing technique used primarily to prevent the fabric from rolling or shifting. It involves stitching the seam allowance to the garment layer, usually on the facing or lining, keeping everything in place while providing a clean finish. This technique is particularly useful for necklines, armholes, and other curved areas.
Why is Understitching Important?
Using understitching in your sewing projects offers several benefits, especially for those who appreciate the principles of slow fashion:
- Improves Appearance: Understitching creates a neater finish by preventing the facing from rolling outward.
- Enhances Durability: This technique reinforces the seams, making your garments last longer.
- Boosts Confidence: Knowing how to add professional touches can elevate your DIY sewing skills.
How to Do Understitching (Step by Step)
-
Sew and Press the Seam
-
After joining your garment and facing, press the seam flat first. This makes the next steps more precise.
-
-
Press the Seam Allowance Toward the Facing
-
Push both the seam allowance and facing away from the garment body.
-
-
Stitch Close to the Seam Line
-
Sew a line of stitching about 2mm–3mm (1/8 inch) from the seam, catching both the facing and the seam allowance.
-
Make sure you’re not stitching through the garment exterior.
-
-
Press Again
-
Iron the facing so it stays firmly to the inside. This final press locks in the neat finish.

Common Sewing Mistakes with Understitching
Beginners often skip understitching altogether or make errors that reduce its effect. Here are mistakes to watch for:
- Sewing too far from the seam line (less effective).
- Forgetting to press before and after stitching.
- Using long stitches that don’t hold the seam allowance firmly.
- Letting the facing shift while sewing, which causes puckering.
By avoiding these sewing mistakes, you’ll notice a dramatic improvement in the quality of your garments.
When to Use Understitching
Not every seam requires understitching, but it’s especially useful for:
- Necklines
- Armholes
- Collars
- Waistbands
-
Any curved or visible edge
Think of it as an insurance policy—taking just a few minutes to understitch saves hours of frustration later.
