What Are Sewing Pattern Notches?
Share
If you’ve ever used a sewing pattern, you’ve probably noticed small marks or little cuts along the edges of the pattern pieces. These are called sewing notches, also known as “sewing notches,” and they are extremely important for sewing garments correctly.
What Are Sewing Notches?
Sewing notches are small marks placed on a pattern to help align fabric pieces during sewing. They act as guides that show where seams, darts, pleats, gathers, or matching points should connect.
Notches help make sewing easier and improve the final fit of the garment.
Why Are Notches Important?
Notches help you:
- Match front and back pieces correctly
- Align sleeves with armholes
- Position darts and pleats accurately
- Prevent twisting or uneven seams
- Sew garments with more precision
Without notches, it’s much easier to sew pieces incorrectly.
Where Are Notches Placed?
Notches are usually placed on:
- Armholes
- Side seams
- Sleeves
- Waistlines
- Center front or center back
- Collar and neckline areas
- Matching points between pattern pieces
Single notches and double notches are often used to identify different sections of the garment.

How to Mark Sewing Notches
There are different ways to mark notches:
1. Small Cuts
The most common method is making a tiny cut outward from the seam allowance.
2. Fabric Markers
You can transfer notches using tailor’s chalk, washable pens, or tracing paper.
3. Clips or Pins
Some sewists use clips or pins as temporary guides.
Tips for Using Notches
- Always transfer notches before sewing
- Keep cuts small to avoid damaging the fabric
- Double-check matching points before stitching
- Use notches together with grainlines and seam allowances
Final Tip
Small details make a big difference in sewing. Learning how to use sewing notches properly will help your garments look cleaner, more professional, and fit better.
