What you’ll make
Create a clean raw-edge finish that helps prevent fabric from fraying during wear and washing, using a regular sewing machine.
This compact technique class compares several machine-made overcast finishes so you can choose one suited to your fabric and equipment.
What you’ll learn in this class
- Understand what overcasting does and where the stitches sit on a raw edge.
- Use a basic zigzag on a domestic sewing machine.
- Test stitch width and length on a scrap.
- Identify overcasting stitches for woven and stretch fabrics.
- Use an overcasting foot to guide the edge and reduce puckering.
- Compare regular-machine finishes with serger overcasting.
Where to use it
Overcasting is useful for cotton, linen, poplin, canvas, and other fabrics whose raw edges may fray. Choose an elastic overcasting stitch for stretch knits.
Fabric weight and stretch affect the result, so the class emphasizes testing the available stitches on a matching scrap first.
